Optical fiber transceivers are generally used in actual network environments where Ethernet cables cannot be covered and optical fibers must be used to extend the transmission distance. At the same time, they have also played a huge role in helping to connect the last mile of optical fiber lines ...

We have often heard of fiber optic switches and fiber optic transceivers. Among them, fiber optic switches are high-speed network transmission relay equipment, also called fiber channel switches and SAN switches. Compared with ordinary switches, they use fiber optic cables as transmission equipme...

Before understanding PoE switches, we must first understand what PoE is. PoE is a power supply over Ethernet technology. It is a method of remotely supplying power to connected network devices (such as Wireless LAN AP, IP Phone, Bluetooth AP, IP Camera, etc.) on a standard Ethernet data cable, el...

1.1 Basic function module The optical fiber transceiver includes three basic functional modules: photoelectric media conversion chip, optical signal interface (optical transceiver integrated module) and electrical signal interface (RJ45). If equipped with network management functions, it also inc...

Optical fiber fusion splicing process Optical fiber connection methods can be divided into two types: one is the permanent connection method that cannot be disassembled and assembled once connected, and the other is the connector connection method that can be repeatedly disassembled and assembled...

The PoE switch is a switch that supports power supply to the network cable. Compared with the ordinary switch, the power receiving terminal (such as AP, digital camera, etc.) does not need to be wired for power supply, and the reliability of the entire network is higher. The difference between P...
