As the conversion equipment of photoelectric signal, optical fiber media converter has become one of the important technical equipment in the field of social communication. Optical fiber media converter is a kind of communication equipment which can convert short distance Ethernet electric signal and long distance optical signal. One end of it is optical fiber interface and the other is Ethernet interface.

The emergence of optical fiber media converter is to make up for the problem of short transmission distance of network cable (the maximum is no more than 100m). In the application scenarios such as school, residential area, high-rise building and commercial square, it is impossible to use network cable to wire, which requires optical fiber to extend the transmission distance.

Therefore, optical fiber media converter (photoelectric converter) was born.

Optical fiber media converter has the characteristics of wide frequency band, low loss, short delay, reliable performance, low cost and convenient maintenance. According to the properties of optical fiber used, it can be divided into single-mode media converter and multimode media converter. The coverage of single-mode media converter is 20km-120km, while multimode media converter is only 550m-5km;

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

According to the transmission rate, it can be divided into 10 / 100M, 10 / 100 / 1000M and 1000M optical fiber media converter. ETU-Link can provide optical fiber media converter with the above three rates..

The applications of optical fiber media converter are mainly between switches, between switches and computers, between computers and computers, relay transmission, conversion between optical fiber modes (multimode and single mode), and WDM transmission (to solve the problem of insufficient optical fiber).

With the development of communication technology, optical fiber media converter products are constantly improving and upgrading. Optical fiber media converter are mostly used in the corridor or outdoors, and the power supply is very complex and unstable. In many areas, ultra-high temperature and ultra-low temperature weather will occur, and the impact of lightning and electromagnetic interference often exists. In this regard, ETU-Link optical fiber media converter in the use of key components, circuit layout and welding and structural design are strictly controlled to ensure the quality of products.

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