Function and Classification of Optical Fiber Transceivers

- Sep 16, 2019-

Optical transceiver is an Ethernet transmission media conversion unit that interchanges short-distance twisted pair signal and long-distance optical signal. It is also called Fiber Converter in many places. Products are generally used in practical network environments where Ethernet cables cannot be covered and optical fibers must be used to extend transmission distances, and they are usually located in access layer applications of broadband MAN, such as high-definition video image transmission for monitoring security projects, and help connect the last kilometre of optical fibers to MAN and beyond. Layer network also plays a huge role.

I. The Role of Optical Fiber Transceivers

Optical transceivers are generally used in the actual network environment where the Ethernet cable cannot be covered and the transmission distance must be extended by optical fibers. They also play an important role in helping to connect the last kilometer of optical fibers to the metropolitan area network (MAN) and the outermost network. With optical transceivers, the system needs to be upgraded from copper wire to optical fiber, providing a cheap solution for users who lack funds, manpower or time. The function of optical transceiver is to convert the electrical signal we want to send into optical signal and send it out. At the same time, it can convert the received optical signal into electrical signal and input it to our receiving end.

Classification of optical transceivers

  1. By nature

According to the properties of optical fibers, it can be divided into multi-mode optical transceivers and single-mode optical transceivers. The difference between them is that the transmission distance is different. Multimode transceivers generally have a transmission distance of 2 km to 5 km, while single-mode transceivers can cover a range of 20 km to 120 km.

2. Distribution by Receiving and Sending Data

Single-fiber transceiver and double-fiber transceiver are classified according to the required optical fibers. Single-fiber transceiver receives the transmitted data and transmits it on one optical fiber, while double-fiber transceiver receives the transmitted data and transmits it on one optical fiber.

3. Distribution by Network Management

According to network management, it can be divided into network management type optical fiber transceiver and non-network management type optical fiber transceiver.

4. According to the type of management

According to the type of management, it can be divided into two types: network management Ethernet optical fiber transceiver and non-network management Ethernet optical fiber transceiver. The network management Ethernet optical fiber transceiver supports telecommunication-level network management, while the non-network management Ethernet optical fiber transceiver sets the mode of port operation through the hardware dial switch, namely plug-and-play.

5. According to the mode of work

According to the mode of work, full duplex means that when data transmission and reception are diverted by two different transmission lines, both sides of the communication can send and receive at the same time. Such transmission mode is full duplex.
