As the conversion equipment of photoelectric signal, optical fiber transceiver has become one of the important technical equipment in the field of social communication. Optical transceiver is a communication device that converts short distance Ethernet electrical signals to long distance optical signals. One end of the optical transceiver is an optical fiber interface, and the other end is an Ethernet interface.

The optical transceiver is designed to make up for the short transmission distance of the network cable (the maximum is not more than 100M). In the application scenarios of schools, residential areas, high-rise buildings, commercial plazas, etc., the network cable cannot be used only for wiring, which requires optical fiber to extend the transmission distance. Thus, the optical fiber transceiver (photoelectric converter) was born.

Optical fiber transceiver has the characteristics of wide band, low loss, short delay, reliable performance, low cost, convenient maintenance, etc. According to the nature of optical fiber used, it can be divided into single-mode optical fiber transceiver and multi-mode optical fiber transceiver. The coverage range of single-mode optical fiber transceiver is 20KM-120KM, while that of multi-mode optical fiber transceiver is only 550M-5KM;

According to the number of optical fibers, it can be divided into single fiber transceiver and dual fiber transceiver. The single fiber transceiver generally provides a SC optical fiber interface, which uses wavelength division multiplexing technology to realize the reception and transmission of data on one optical fiber, while the dual fiber transceiver realizes the reception and transmission of data on two optical fibers respectively.

According to the transmission rate, it can be divided into 10/100M, 10/100/1000M and 1000M optical fiber transceivers. The above three kinds of optical fiber transceivers can be provided.

The application of optical fiber transceiver mainly includes switch to switch, switch to computer, computer to computer, relay transmission, conversion between optical fiber modes (multi-mode, single-mode), and wavelength division multiplexing transmission (to solve the problem of insufficient optical fiber).

With the development of communication technology, optical transceiver products are also constantly improving and upgrading. Optical fiber transceivers are mostly used in corridors or outdoors, and the power supply is very complex and unstable. In many areas, ultra-high and ultra-low temperature weather conditions will occur, and the impact of lightning and electromagnetic interference often exists. For this, the use of key components, circuit layout and welding, and structural design of optical fiber transceivers are strictly checked to ensure product quality.

For a long time to come, the optical transceiver products will still be an indispensable part of the actual network construction. It is believed that the optical transceiver products in the future will continue to develop in the direction of high intelligence, high stability, low delay, network management and low cost.

Introduction and Application of EPON Optical Module and GPON Optical Module

Speaking of PON optical module, let's first understand what PON is. PON refers to passive optical network, which is an important way for broadband access network to carry services.

PON technology originated in 1995. Later, according to the difference between the data link layer and the physical layer, PON technology was gradually subdivided into APON, EPON, and GPON, among which APON technology has been eliminated in the market due to its high cost and low bandwidth.
