Fiber optic transceiver (FIB) is a kind of Ethernet transmission media conversion unit that interchanges short-distance twisted pair electrical signals with long-distance optical signals. In many places, it is also called Fiber optic Converter. The product is generally applied in the actual network environment where Ethernet cable cannot be covered and optical fiber must be used to extend the transmission distance, and is usually located in the access layer application of broadband MAN. For example: monitoring the transmission of high-definition video images for security projects; it also plays a huge role in helping to connect the last mile of fiber-optic lines to metropolitan networks and beyond.

Role

Fiber-optic transceivers are typically used in real-world network environments where Ethernet cables cannot be covered and optical fibers must be used to extend transmission distances. They also play a huge role in helping connect the last kilometer of optical fiber lines to the metropolitan area network and beyond. Fiber-optic transceivers also provide an inexpensive solution for users who lack the money, manpower or time to upgrade their systems from copper wire to fiber. The purpose of the fiber optic transceiver is to convert the electrical signal that we‘re going to send into an optical signal, and send it out, and at the same time, convert the optical signal that we‘re going to receive into an electrical signal that we‘re going to send to the receiver.

The characteristics

Fiber optic transceivers usually have the following basic characteristics:

1. Provide ultra-low time delay data transmission.

2. Fully transparent to network protocols.

3. The special ASIC chip is used to realize fast transmission of data line. Programmable ASIC concentrates multiple functions on a chip, which has the advantages of simple design, high reliability, less power consumption, etc., so that the equipment can get higher performance and lower cost.

4. Rack-type equipment can provide hot plug function for easy maintenance and uninterrupted upgrade.

5. Network management equipment can provide network diagnosis, upgrade, status report, abnormal situation report and control functions, can provide a complete operation log and alarm log.

6. The equipment mostly adopts 1+1 power supply design, supports ultra-wide power supply voltage, and realizes power protection and automatic switching.

7. Supports ultra-wide operating temperature range.

8. Support a complete transmission range (0 ~ 120 km).
