Comparison of the advantages of fiber optic transceivers and optical transceivers

A fiber optic transceiver is an Ethernet transmission media conversion device that interchanges twisted-pair electrical signals for short-distance transmission and optical signals for long-distance transmission. It is called a photoelectric converter in some places.

In order to ensure full compatibility with network devices such as network cards, repeaters, hubs and switches of other manufacturers, fiber optic transceivers are completely transparent to network protocols.

According to different characteristics, there are many types of fiber optic transceivers:

According to the transmission mode, it can be divided into single-mode fiber optic transceivers and multimode fiber optic transceivers;

According to the number of transmission cores, it can be divided into single-fiber optical transceivers and dual-fiber optical transceivers;

According to the rate, it can be divided into single 10M, 100M fiber optic transceivers, 10/100M adaptive fiber optic transceivers, 1000M fiber optic transceivers and 10/100/1000 adaptive fiber optic transceivers;

According to the structure, it can be divided into desktop optical fiber transceiver and rack optical fiber transceiver;

According to the gateway type, it can be divided into unmanaged fiber optic transceivers and network managed fiber optic transceivers;

According to the power supply, it can be divided into built-in power fiber optic transceivers and external power fiber optic transceivers;

According to the working mode, it can be divided into full-duplex fiber optic transceivers and half-duplex fiber optic transceivers.

What is an optical transceiver?

The optical transceiver is the transmission equipment in the optical communication system, mainly for photoelectric conversion and transmission functions. It is generally used in telecommunications, electric power, monitoring, industrial control, video transmission and other functions, and has a wide range of applications in various industries.

The optical transceiver is divided into a transmitter and a receiver. The transmitter converts the electrical signal into an optical signal; the receiver converts the transmitted optical signal into an electrical signal and transmits it to the next-level equipment. It mainly uses the optical transmission characteristics to achieve the purpose of long-distance transmission through signal modulation photoelectric conversion and other technologies.

With the wide application of optical transceivers, there are more and more classifications of optical transceivers, and the functions of different types of optical transceivers are also different.

According to the transmission signal mode, it can be divided into analog optical transceiver and digital optical transceiver;

According to the application technology, it can be divided into PDH (Plesiochronous Digital Hierarchy, quasi-synchronous digital series) optical transceiver and SDH (Synchronous Digital Hierarchy, synchronous digital series) optical transceiver;

According to the transmission interface, it can be divided into video optical transceivers, audio optical transceivers, data optical transceivers, switching optical transceivers, telephone optical transceivers, etc.

The difference between optical fiber transceiver and optical transceiver:

1. Both the transceiver and the optical transceiver can perform photoelectric conversion, but the optical fiber transceiver cannot process data, and it can only connect point-to-point. The optical transceiver can realize the multiplexing and demultiplexing of data signals, so it is slightly more powerful in function.

2.The output from the optical transceiver is multiple pairs of E1 lines. SDH and PDH optical transceivers are mainly used for telecom operators to provide multi-point-to-point data circuits; video optical transceivers are mainly used in security monitoring, distance education, video conferencing and other fields that require high timeliness in video transmission. Transmit control, switch, voice, Ethernet and other signals to meet the needs of multi-service applications, which is not available in transceivers.
