Characteristic and Function of Photoelectric Converter

- Sep 27, 2019-

I. Performance characteristics

Since the discovery of optoelectronic effect, optoelectronic converters have made rapid progress. At present, various kinds of optoelectronic converters have been widely used in all walks of life. Commonly used photoelectric effect converter devices are photoresistor, photomultiplier, photovoltaic cell, PIN tube, CCD and so on. The wide application of photoelectric converters is mainly due to the following characteristics:

1. Optical port configuration is flexible, supporting SC/ST/LC, single/multi-mode.

2. Low Voltage Redundant DC Dual Power Supply or AC Power Supply

3. IP30 and above protection level

4. The working temperature can support - 40 C to 75 C.

Two, role

Photoelectric converter (also known as optical transceiver) is a kind of fast ethernet, which can be divided into 100-mega optical transceiver and Giga optical transceiver. Its data transmission rate is up to 1 Gbps. It still adopts CSMA/CD access control mechanism and is compatible with existing ethernet. With the support of wiring system, the original fast Ethernet can be smoothly increased. Gigabit network technology has become the preferred technology for new network construction and renovation, thus improving the performance requirements of integrated wiring system. Among them, there are industrial and commercial ones. Generally commercial ones have lower parameters and narrower scope. Industrial ones have better performance and are suitable for industrial environment.

Photoelectric converters are generally used in practical network environments where Ethernet cables cannot be covered and optical fibers must be used to extend transmission distances. At the same time, they also play an important role in helping to connect the last kilometer of optical fibers to MAN and the outermost network. With optoelectronic converters, 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 photoelectric converter 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.

The function of photoelectric converter is introduced above. It is believed that in the course of the continuous development of optical fiber technology in the future, the application of optoelectronic converter equipment will become more and more common.
