There are many products in the security industry that are not industry originals. Optical transceivers are a type of equipment that has been introduced into the security industry from the broadcasting and TV industry. In the 1990s, the simplest analog optical transceiver was introduced into the security industry and began to be used in analog monitoring systems. By 2001, digital optical transceivers began to appear and quickly replaced the analog optical transceiver market. Afterwards, the development of optical transceivers in the security industry experienced a blowout-type development and the number of enterprises in the industry increased rapidly. Nowadays, the halo of digital optical transceivers has also begun to decline, and prices have begun to decline. With the increase of enterprises in the industry, expansion of product varieties, and enhancement of the competitiveness of substitutes, optical transceivers are displayed in terms of products, market environment, and consumer groups. Out into the mature characteristics.
The development and variety of optical transceivers Optical transceivers can be said to be senior level devices in the field of surveillance. In the CCTV closed-circuit TV monitoring system of the first generation before 2000, its equipment configuration included optical multiplexers in addition to analog cameras, picture splitters, video cables, matrices, and VCRs. The analog optical transceiver is mainly used to modulate the baseband video, audio, and data transmission signals to a carrier in the transmitting end using analog FM, amplitude modulation, and phase modulation. The optical receiver demodulates and restores the corresponding baseband video, audio, and data. signal. The CCTV system has nothing to do with the computer and the network. The optical transceiver is a member of the analog family since its birth.
In 2001, analog optical transceivers could not meet the requirements of large-capacity, multi-service transmission, multi-path crosstalk, attenuation, and aging, poor stability and interchangeability, and inconvenience in after-sales service. Digital optical transceivers began to enter the market instead. Analog optical transceiver. The digital video transmitter consists of transmitter and receiver. The function of the transmitting end is to amplify the analog signal of the user end, A/D conversion, multiplexing, etc., and then convert the electric signal into an optical signal through the electro-optical conversion and transmit it from the optical fiber to the receiving end. At the receiving end, the opposite processing is performed, and the optical signal is first converted into an electrical signal. The electrical signal is sent to the user through demultiplexing, D/A conversion, and amplification and filtering. The digital optical transceivers have large transmission capacity and many types of services, which increase the utilization of optical fiber bandwidth and improve the cost-effectiveness. It also improves the signal quality to a higher level. By 2007, it occupied almost the majority of the optical transceiver market.
Whether it is an analog optical transceiver or a digital optical transceiver, their role is the transmission of analog signals. It is used in conjunction with analog signal acquisition equipment.
In the field of video surveillance, optical transceivers can be classified into peer-to-peer, node-based, and point-to-point convergent optical transceivers based on networking. The digital optical transceiver is divided into an image compression digital optical transceiver and a non-compressed digital optical transceiver in accordance with the transmission technology. Among them, the image compression digital optical transceiver can use the existing redundant channels of telecommunication transmission equipment to transmit monitoring images, which brings convenience to engineering applications. However, its fatal weakness is that it cannot guarantee the real-time nature of image transmission, while non-compressed digital optical transceivers can use high data rates to ensure the transmission quality and real-time performance of video signals.
The technical bottlenecks currently faced by optical transceivers are mainly the capacity and service expansion and application modes. The service bandwidth that the optical fiber can bear is very big, how to make full use of the optical fiber bandwidth, realize the transmission of large capacity, more business, every professional manufacturer is thinking constantly. In addition to optical transceivers, current optical fiber transmission solutions include optical arrays, video codecs and switches, Ethernet passive optical networks (EPON)+video codecs, and UTN integrated services optical transmission networks.
Different types of optical transceivers require different applications in the field of video surveillance. Because video surveillance is a complex system project, different environments have different requirements for optical transceivers.
The monitoring of urban roads, highways, rail transit, etc. is currently concentrated in key sections such as toll stations, bridges, tunnels, and stations. The optical fiber resources are relatively tight. The requirements for optical transceivers are large video capacity and transmission distance, so node-type optical transceivers are generally used. And optical transmission switching platform. In terms of transmission interface requirements, in addition to large-capacity video ports, there are often two-way intercoms such as interfaces that support AIPHONE intercom, telephone interfaces, and 10/100M Ethernet interfaces that meet automation requirements. In these application areas, the customer's requirements for product quality, brand, and service are relatively high.
Video surveillance such as “Safe City†is mainly aimed at industrial parks, key locations, public places, finances, and business establishments. These applications have different requirements for optical transceivers. They are primarily video-based in function, and are supplemented by reverse control data interfaces. Control lens head and alarm switch interface, there are audio monitoring requirements. In these fields, peer-to-peer optical transceivers have been widely used and formed a mature networking method. However, peer-to-peer optical transceivers can only operate one-to-one. In "safe cities" and other projects, only star-type transmission networks can be formed. That is, the monitoring signals of each monitoring point must be transmitted to the police station through independent optical fibers. The larger, the more fiber resources are occupied, which is a waste of fiber. This part of the customer is more sensitive to price.
Some manufacturers have developed new types of active convergence optical transceivers for projects such as “Safe City†to address the issue of waste of optical fibers. The optical network architecture of this optical transceiver is mainly divided into two parts. The front-end convergence part is a star network and the back end is a chain type. In the network, the work method is that multiple front-end devices respectively transmit signals to the convergence end, and then transmit the signals through a core fiber to the back-end monitoring center. This way, backbone fiber can be saved.
At present, peer-to-peer optical transceivers have been introduced for a long time, and manufacturers use technology upgrades to improve reliability and performance parameters. The multi-service network switching platform optical transceiver is a major product of manufacturers with strong R&D capabilities in recent years. Compared with the traditional optical transceiver, it only serves as a transmission channel. Platform-based products have a wider range of functions, including video transmission, switching, and management and storage. Optical transceivers based on EPON technology have also begun to receive attention from manufacturers. This kind of product can provide low-cost and reliable solutions for large-capacity front-end video access.
After five years of rapid development, the optical industry has undergone tremendous changes. According to a survey by the reporter, the optical transceiver industry currently exhibits the following features.
Sub-scale shuffling. Because although the price of small factory products is now low, the quality system, production system, and after-sales service system of large manufacturers are all difficult for small factories to achieve.
The competition of alternatives has begun to reveal that the development of IP surveillance has affected the future market of optical transceivers. This has become a hot topic in the industry. Beijing Guangqiao Zhang Naixian pointed out: "Without doubt, with the acceleration of the IP process, the proportion of video optical transceivers in the entire security monitoring system is shrinking." Shenzhen Nuolong Zhou Shuai also agreed with this view, but that although the ratio is reduced , but the total is still increasing. Feng Xiaowei of Frog Vision Communications believes that the acceleration of the IP process has not had much impact on the optical transceiver market because the market capacity is continuously expanding. At the same time, the development of IP technology has not fully satisfied the needs of customers in terms of image quality. The video market demand is still great. Digitization is a trend, but the transition from non-compression to compression should continue for several more years. For this issue, Chengdu Weidi Liu Mingxue thinks that the popularity of IP surveillance may cause the optical transceiver to die in the future, but it also points out that some technical problems existed in IP monitoring, such as the unstable transmission speed caused by the bandwidth limitation and the compression transmission technology of optical transceivers. The increase may make the future of the two converge toward convergence instead of competition. Li Tianyou of Tiandi Weiye believes that the development of IP will definitely not affect the optical transceiver market based on optical fiber transmission. On the contrary, this market will have room for further improvement because the advantage of optical transmission is that IP transmission cannot be replaced. Clear video, all-real-time transmission, smooth control, and no delay are the current technologies that IP transmission cannot achieve. Lu Aiming, the product line director of Hikvision, also indicated that he does not believe that the video end will be washed out. Because current network front-end equipment will not completely replace analog products in the short term due to various reasons; secondly, analog video solutions have mature and economical advantages, and are especially suitable for small and medium-sized monitoring projects; in addition, for projects built for use. It is still more convenient for maintenance and expansion to follow the previous fiber transmission scheme.
Consumer demand continues to increase. Currently, consumers in the industry are in a state of polarization. Some consumers are more concerned about prices. Li Tianyou, product manager of Tiandi Weiye, said that at present, a large part of the customers in the optical transceiver market are concerned about the price and then the quality, service and other factors. At the same time, another part of customers first pay attention to product quality. Chengdu Weidi Liu Ming said that the petroleum and petrochemical fields have high requirements on the quality of node-type optical transceivers. Users in this field not only hope that the optical transceivers used in the field will have better integration of video, audio, intercom, telephone, and Ethernet functions, but also There are high requirements for the stability of each type of signal transmission.
"High-definition", "high-end", "stable" new highlights Video surveillance industry, by the camera "high-definition", the video and optical industry in the "high-definition" concept has also begun to rise. Feng Xiaowei, Product Manager of Frog Vision Communications, said, “Although there are still some honesty at the current application level, with the passage of time, there will certainly be more mature applications for high-definition video services.â€
Frog Vision Communications has recently launched high-definition video optical transceivers such as HDMI, DVI, SDI, and other industry-standard interfaces. With the continuous development of optoelectronics technology, frog visual communications optical and optical products continue to try more high-speed optical devices (1.25G/2.5G/5G/10G), in addition to the full use of coarse wavelength division and dense wavelength division optical fiber wavelength multiplexing technology In addition, high-capacity transmission of at least 256 channels of images can be achieved on a 1-core fiber.
Tiandi Weiye will launch a high-definition optical transceiver (SDI optical transceiver) in the near future. This optical transceiver not only supports one HD SDI signal, but also can provide one reverse data. It can not only support SDI HD cameras, but also support SDI HD dome cameras and receive The end can realize the function of video conversion alone, and can convert all SDI to HDMI and VGA signals.
Jiangsu Xinchuang also introduced a full range of HD optical transceivers such as HDMI, DVI, VGA, YPbPr, RGBHV, and 3G/HD/SD-SDI.
In addition to the "high-definition" wind, the optical transceiver industry is still scraping the "high-end" wind. As there are many new entrants in this industry, the competition in the low-end market is very fierce. Some mainstream manufacturers have begun to position the market segments in high-end customers such as expressways and industrial enterprises.
Chengdu Micro-Di has launched a large-capacity node transmission system for applications such as highways and other applications. The system supports up to 128 access points on a single fiber, and each access point supports 1 to 2 channels. Video, 1-way independent data function and 1-way audio and 2-way shared data can support ring self-healing network. The system uses a broadcast-TV-level lossless compression solution.
Infinera has also launched a 100-node optical transceiver for high-end users. It can connect up to 100 nodes through a single core fiber and can form a self-healing ring. It uses a small amount of fiber to build high-capacity, highly reliable video, audio, and data transmission systems. At present, Infinera is strengthening the R&D of multi-nodes and optical transceivers based on PON technology. The main features of these products are: saving optical cables, transmitting large amounts of video, flexible access, easy maintenance, and perfect network management functions. It is suitable for video surveillance systems with a large number of videos and cross-region cities. It can also be applied to video surveillance of highways, high-speed railways, subways and other transportation facilities.
In addition, the stability of the product has become a concern for optical transceiver manufacturers. Beijing Guangqiao launched its video optical transceiver with fault pre-diagnosis in early 2010. This optical transceiver can alarm in advance before the optical transceiver function fails, prompting the user to replace, so that the system can be avoided.
During the product's mature period, the company seeks diversified development to broaden the market. Each type of product has its own inherent life cycle, and optical transceivers are no exception. If the product life cycle of the optical transceiver is divided into four stages: investment period, growth period, maturity period, and recession period, from the perspective of the current industry structure, the optical transceiver has just entered the mature stage. Feng Xiaowei, product manager of Frog Vision Communications, said, “With the continuous expansion of the security industry, the overall trend of the optical transceiver market in the next three years should continue to maintain a stable growth. At present, the market demand for optical transceiver products is still steadily increasing, and the market gradually The products will be gradually subdivided, and each manufacturer will have its own product line.†But companies also expect that in the distant future, the optical transceivers may end in decline. Zhang Naixian of Beijing Guangqiao believes that "the video light end opportunities have existed for a long time, but it is not a future business direction from the technical direction. Therefore, optical transceiver manufacturers should not have unrealistic fantasies." Liu Mingxue of Chengdu Microdi believes: "The optical transceiver industry cannot Support the growth of the next 20 to 50 years."
A product just entering the mature period is often the best time for corporate decision makers to consider the future development direction of the company and to find the future profit growth point.
Infino Marketing Director Li Zhihong believes that several optical transceiver manufacturers with strengths should promote Optical Multiplexer as a system solution instead of a single peer-to-peer video transmission function, and can integrate video, audio, network, and high-definition video services through optical fiber cable management. At present, Infinera's marketing strategy is based on solutions, combined with current IP video solutions, to provide users with a large-scale video integrated management platform based on fiber optic cable.
Beijing Guangqiao Zhang Naixian pointed out that Beijing Guangqiao is committed to providing customers with a complete set of solutions for the new generation of security monitoring systems, namely the full set of intelligent video analytics security monitoring. Optical transceivers are just a very competitive product in many product lines.
Frogwatch has changed its product positioning, and it wants to transform from the original product provider to a solution provider. Product Manager Feng Xiaowei told reporters that the company's flagship product is not Guangduan Ji, but VOX-XG open all-digital video management platform. This product is not a simple implementation of video transmission capabilities, but integrated video, data, Ethernet and other business distribution access, multiplexed transmission, private network exchange, network management, multi-stream sharing services, can build a perfect The monitoring platform is particularly cost-effective in large and medium-sized monitoring projects dedicated to private networks. In the near future, FrogView also introduced the VS-iEye intelligent management platform solution, which has been applied. In terms of sales model, the adjustment of frog-watch communication is relatively large, and the original project sales will be adjusted mainly to channel sales, and the establishment of better and more extensive cooperation platforms with local distributors will be accelerated.
Nuolong's Zhou Shuai introduced that Nuolong currently provides system platforms such as optical matrix and UTN integrated service optical transmission network in addition to the production of optical transceiver equipment. In the current optical transceiver manufacturers, nandron only launched the all-optical network transmission platform - UTN integrated services optical transmission network. UTN integrated services optical transmission network set image compression codec, optical fiber communication, data transmission, network switching, digital video network storage, data query retrieval playback, multi-level remote control in one, is a fully functional all-digital optical network video surveillance solution .
Li Tianyou of Tiandi Weiye believes that the integration of optical transceivers and other products will be a future development direction, such as optical fiber domes, fiber optic cameras, and fiber optic video encoders. Take fiber optic high-speed ball as an example. The high-speed ball in the world is a high-speed ball on the transmitter module of the optical transceiver. It does not simply put the transmitter of the MINI optical transmitter into the dome. The advantage of this is that The whole ball machine circuit adopts a single chip design. The ball machine circuit and the light emitting end seamlessly integrate with higher integration; convenient installation and appearance; video and control optical fiber lead out, natural lightning protection, and anti-electromagnetic interference, can be used in high pressure places.
The oldest manufacturer of optical transceivers, Chengdu Microdi, has entered the field of cameras and is now carrying high-end positioning high-definition network cameras and analog cameras to enter the international market. Speaking about why he entered the field, General Manager Liu Mingxue said that Weidi hopes to enter more mainstream industries in the field of security monitoring, and use research and development capabilities, brands, and existing management systems to provide industries and customers with more distinctive products. At the same time, MicroDi is also developing a more stable all-digital transmission switching system.
Hikvision, which is a leader in cameras, DVRs, and CCTC's comprehensive surveillance industry, intends to further improve Hikvision's product line by intervening in the development of optical transmission products to enable seamless real-time docking of front-end products and back-end products. In order to provide customers with a set of highly integrated and highly reliable solutions. Lu Aiming, product manager of Hikvision, said that the future improvement of optical transceivers is to understand the actual needs of security monitoring changes, targeted innovation. At present, in the projects of railways, electric power, public transportation, and urban surveillance, the scale of the monitoring system is getting bigger and bigger, and the architecture is becoming more and more complicated; the trend of high-definition video and IP access is also obvious. Ordinary video optical transceivers cannot effectively meet the above requirements and need to be improved in terms of multi-service access capabilities and large-scale networking applications. It is understood that Hikvision has launched a corresponding solution.
Concluding remarks Optical has entered a mature period, at least in the past three years, it will be the company's "cash cow." During the product's mature period, the market surface is blossoming, but in the dark it is surging. As a mainstream manufacturer of optical transceivers, whether it continues to develop optical transceivers or does not invest too much in R&D of optical transceivers are all their own choices. However, as a veteran-class device in the field of video surveillance, Optical transceivers have made indelible contributions to the popularity and development of video surveillance.

Nuolong's Zhou Shuai introduced that Nuolong currently provides system platforms such as optical matrix and UTN integrated service optical transmission network in addition to the production of optical transceiver equipment. In the current optical transceiver manufacturers, nandron only launched the all-optical network transmission platform - UTN integrated services optical transmission network. UTN integrated services optical transmission network set image compression codec, optical fiber communication, data transmission, network switching, digital video network storage, data query retrieval playback, multi-level remote control in one, is a fully functional all-digital optical network video surveillance solution .
Li Tianyou of Tiandi Weiye believes that the integration of optical transceivers and other products will be a future development direction, such as optical fiber domes, fiber optic cameras, and fiber optic video encoders. Take fiber optic high-speed ball as an example. The high-speed ball in the world is a high-speed ball on the transmitter module of the optical transceiver. It does not simply put the transmitter of the MINI optical transmitter into the dome. The advantage of this is that The whole ball machine circuit adopts a single chip design. The ball machine circuit and the light emitting end seamlessly integrate with higher integration; convenient installation and appearance; video and control optical fiber lead out, natural lightning protection, and anti-electromagnetic interference, can be used in high pressure places.
The oldest manufacturer of optical transceivers, Chengdu Microdi, has entered the field of cameras and is now carrying high-end positioning high-definition network cameras and analog cameras to enter the international market. Speaking about why he entered the field, General Manager Liu Mingxue said that Weidi hopes to enter more mainstream industries in the field of security monitoring, and use research and development capabilities, brands, and existing management systems to provide industries and customers with more distinctive products. At the same time, MicroDi is also developing a more stable all-digital transmission switching system.
Hikvision, which is a leader in cameras, DVRs, and CCTC's comprehensive surveillance industry, intends to further improve Hikvision's product line by intervening in the development of optical transmission products to enable seamless real-time docking of front-end products and back-end products. In order to provide customers with a set of highly integrated and highly reliable solutions. Lu Aiming, product manager of Hikvision, said that the future improvement of optical transceivers is to understand the actual needs of security monitoring changes, targeted innovation. At present, in the projects of railways, electric power, public transportation, and urban surveillance, the scale of the monitoring system is getting bigger and bigger, and the architecture is becoming more and more complicated; the trend of high-definition video and IP access is also obvious. Ordinary video optical transceivers cannot effectively meet the above requirements and need to be improved in terms of multi-service access capabilities and large-scale networking applications. It is understood that Hikvision has launched a corresponding solution.
Concluding remarks Optical has entered a mature period, at least in the past three years, it will be the company's "cash cow." During the product's mature period, the market surface is blossoming, but in the dark it is surging. As a mainstream manufacturer of optical transceivers, whether it continues to develop optical transceivers or does not invest too much in R&D of optical transceivers are all their own choices. However, as a veteran-class device in the field of video surveillance, Optical transceivers have made indelible contributions to the popularity and development of video surveillance.
Industrial steel structure buildings have a wide range of uses, and the high cost performance is worth choosing!
Industrial steel structure buildings are used in various industries, and their construction is convenient, and different steel structure buildings can be designed, which can also meet the needs of daily factories. Let's introduce the specific advantages of using steel structure buildings.
Wide range of uses
The scope of application of industrial steel structure buildings is still very wide. In addition to the use of factories as Steel Structure Workshop, some daily storage centers use Steel Structure Warehouse as warehouse, as well as gymnasiums, dormitories, etc., are actually buildings that can use steel structures. And not only the ground floor can be built, as long as the design is reasonable, then high-rise and multi-storey buildings can be constructed and applied.
Simple construction
Compared with traditional building construction, the construction of the steel structure itself is very simple, and all components are prefabricated and have certain standard sizes, which can be installed directly. The construction efficiency is high, and the construction of the plant can be completed in a short time. And generally it can be directly spliced, which greatly shortens the construction time, and the construction of large-scale buildings can be completed in less than one month.
High durability
Industrial steel structure buildings can be used for a long time, not just temporary use for a month or two, and the stability of the steel structure is also guaranteed. Moreover, the daily maintenance of the building is simple, and the design and construction of the building can be completed directly through computer design. Even if it is used in bad weather, there will be no problems, and it is suitable for long-term use.
beautiful and practical
Steel structure buildings come in many different colors, and manufacturers can also provide customized processing services. The design of the building is simple and beautiful, and it can also be decorated internally. Such a building has strong flexibility in use and can meet the requirements of different projects for long-term use.
Cost discount
Industrial steel structure buildings are light in weight, and the price of steel structures is favorable, and the cost performance is still good. Because of the high construction efficiency of its buildings, labor costs are also very cost-effective. It only needs to complete the design and construction, and the building can be put into use immediately, and the overall cost performance is also good.
