The difference between industrial-grade fiber switches and carrier-grade optical fiber transceivers developed and produced by Shenzhen Zhenxin Communication Technology Co., Ltd. is a confused issue for many customers. The appearance is the same. The transmission signal protocols are the same as fiber-to-the-network. How do you have fiber switches and fiber transceivers? What is the difference between two names? Shenzhen Zhenxin Communication Technology Co., Ltd. has more than 20 professional R&D technical teams and is also the leading brand of fiber optic communication products. After the company's technical staff collected the customer's questions, a professional explanation was given.
We analyze from the following professional perspectives:
The first use of the environment: fiber optic transceivers are generally used in relatively good environment: such as campus, community, security engineering, network video, network audio and other signal transmission. Generally used for security monitoring and renovation projects. Both apply to scenarios that exceed the Ethernet cable (network cable) coverage and require the use of fiber as the transmission medium in the network environment. For example, many of the mentioned networking modes of Internet cafes use fiber transceivers, and many LAN cell networks, campus networks, and enterprise networks require fiber transceivers for networking. However, since fiber optic transceivers need to be interconnected with network devices such as network cards, hubs, switches, and routers, it must comply with the relevant standards of Ethernet, and at the same time, electromagnetic radiation protection should also comply with relevant regulations.
Industrial fiber switches are generally used in outdoor environments such as electricity, wind power, mining, tunnels, rail transit, large financial systems, thermal power plants, and long-distance outdoor component network groups. Ring network, substations and other harsh environments; the more important point is that fiber switches have lightning protection, surge-proof ultra-low latency and elastic caching technology: adopting "storage and forwarding" mode, seamlessly connecting different rate devices, and adaptive operation mode support Wide range of AC and DC input support internal isolation, redundant dual power input, power supply support overload protection, anti-reverse protection, in line with the industry's four electromagnetic compatibility requirements super strong lightning protection function: the use of imported lightning protection devices, lightning protection can be Anti-induction high voltage, four-level lightning protection power supply fanless efficient cooling, reduce repair time IP40 shell protection level, able to withstand the test of harsh environments and other functions. This is not available in fiber optic transceivers.
The optical fiber transceiver is very familiar to everyone is not to repeat, then please refer to the detailed parameters of the fiber switch, take the fiber switch we produced by Shenzhen Zhenxin Communication Technology Company as an example:
