What are the functions of switches and fiber optic transceivers? Fiber optic transceivers are just a kind of photoelectric conversion equipment, only a means to extend the transmission distance because the transmission distance is too long; and the Ethernet switch is a network An Ethernet-connected device for internal data exchange.

The difference between fiber optic switches and fiber optic transceivers is:

1. Optical fiber switch is a high-speed network transmission relay device. Compared with ordinary switches, it uses optical fiber cable as the transmission medium. The advantages of optical fiber transmission are fast speed and strong anti-interference ability;

2. Optical fiber transceiver is an Ethernet transmission media conversion unit that interchanges short-distance twisted-pair electrical signals and long-distance optical signals. It is also called a photoelectric converter (Fiber Converter) in many places. ;

3. The fiber optic switch uses the fiber channel with high transmission rate to connect with the server network, 8-port fiber optic switch or the internal components of the SAN network. In this way, the entire storage network has a very wide bandwidth, which provides a guarantee for high-performance data storage. ;

4. Optical transceivers provide ultra-low latency data transmission and are completely transparent to network protocols. A dedicated ASIC chip is used to realize wire-speed data forwarding. Programmable ASIC integrates multiple functions into one chip, and has the advantages of simple design, high reliability, and low power consumption, which can enable the device to obtain higher performance and lower cost.

If the Ethernet network is too large and the transmission distance has exceeded the distance that the electrical signal can transmit, the electrical switch port of the Ethernet switch needs to perform photoelectric conversion, so you need to use the Ethernet fiber optic transceiver to extend your transmission distance. Electrical signals are converted into optical signals for long-distance transmission.
