Take you to interpret fiber optic transceivers in one minute

Optical fiber transceiver is a communication device that converts short-distance Ethernet electrical signals and long-distance optical signals to each other to ensure smooth transmission of data packets between two networks. It has two types of ports, one end is an optical fiber interface, One end is an Ethernet interface.

As far as fiber optic ports are concerned, there are two types, one is a direct plug-in fiber optic patch cord (SC, ST, etc. adapters), and the other is an optical plug-in module (SFP, SFP+, etc.). As for the network port, it is converted to RJ4 network cable design. So what are its features and applications?

SFP Fiber Transceivers

The fiber optic transceiver has the characteristics of low loss, wide frequency bandwidth, low cost, convenient maintenance, short delay, and reliable performance.

Optical fiber transceivers can be divided into three types according to the transmission rate: 10/100M, 10/100/1000M, and 1000M.

According to the nature of the fiber used, it can be divided into: single-mode fiber transceiver and multi-mode fiber transceiver, among which the multi-mode transceiver is only 550M-5KM, while the single-mode transceiver has a wider coverage, ranging from 20KM-120KM;

It is mainly used in switches, computers, and the interconnection between switches and computers. In addition, it is also used in high-reliability data transmission fields such as telecommunications, railways, shipping, and cable TV. It is generally used in long-distance transmission schemes.

Fiber Transceiver

Take SFP transceivers as an example, SFP transceivers can be interconnected through optical modules, which are different from ordinary fiber optic transceivers only with optical ports. It is flexible in transmission rate, working distance and fiber network type, providing maximum convenience for fiber-to-copper Ethernet conversion applications.

It also has five features:

1. High flexibility and hot-pluggable SFP ports;

2. 1600byte (byte) large data packet transmission;

3. Full-duplex flow control, half-duplex back pressure;

4. Link fault pass-through (LFPT);

5. Full LEDs indicate power and network status.

Mainly used in telecommunications networks, schools, offices and Internet cafes and other fields.
