Common Sense of the Fiber Optic Transceiver

Fiber optic transceiver is an indispensable device in network data transmission. So, what is a fiber optic transceiver? What dose fiber optic transceivers consist of? How are fiber optic transceivers used? What role does the fiber optic transceiver play in the data transmission process? Next, PRIMUSIT will talk about the basic knowledge about it.

1. What is a fiber optic transceiver?

Fiber optic transceiver is a kind of ethernet transmission media conversion unit that converts the short-distance twisted pair electrical signal and long-distance optical signal, and in many places it is also called a photoelectric converter.

Products are generally used in actual network environments where ethernet cables cannot be covered and optical fibers must be used to extend the transmission distance, and they are usually positioned in the access layer application of broadband metropolitan area networks.

Such as: high-definition video image transmission for monitoring security projects. At the same time, it also plays a huge role in helping to connect the last mile line of optical fiber to the metropolitan area network and the outer network.

As one of the professional optical transceiver manufacturers, there are various fiber optic transceiver types in PTIMUSIT, welcome to consult us.

2. The composition of the fiber optic transceiver

The fiber optic transceiver includes three basic functional fiber optic transceiver modules, ie. the fiber optic transceiver module, that is, photoelectric media conversion chip, optical signal interface (optical transceiver integrated module) and electrical signal interface (RJ45). If equipped with network management functions, it also includes a network management information processing unit.

In some large-scale enterprises, optical fiber is used directly as the transmission medium to establish a backbone network during network construction, while the transmission medium of the internal local area network is generally copper wire. How to realize the connection between the local area network and the optical fiber backbone network? This requires conversion between different ports, different line types, and different optical fibers and also ensures the quality of the connection.

The emergence of fiber optic transceivers converts the electrical signals and optical signals of twisted-pair wires to each other, ensuring the smooth transmission of data packets between the two networks. At the same time, it extends the transmission distance limit of the network from 100 meters of copper wires to more than 100 kilometers (single-mode fiber).

3. The method of using the fiber optic transceiver

The general fiber optic transceiver is the same as the general switch. It can be used after powering on, and no configuration is required like optical fiber socket and RJ45 crystal plug socket. But please pay attention to fiber optic transmission and reception. One fiber receives and the other fiber transmits. If it doesn't work, switch them to each other.

4. The function of the fiber optic transceiver

Fiber optic transceivers help to upgrade the system from copper wire to fiber optics, and also provide a low-cost solution for users who lack funds, manpower or time. The function of the fiber optic transceiver is to convert the electrical signal we want to send into an optical signal and send it out. At the same time, it can convert the received optical signal into an electrical signal and input it to our receiving end.
