What is the role of the optical transceiver?

The optical transceiver is the terminal device for optical signal transmission. Due to the improvement of the current technology, the reduction of the price of optical fiber has made it a good application in various fields (mainly in security monitoring), so the manufacturers of optical transceivers are like mushrooming. However, most of the manufacturers here are not fully mature. The development of new technologies requires cost, manpower and material resources. These manufacturers are mostly small and medium-sized enterprises, and various brands have appeared. However, the quality is still similar. Foreign optical transceivers are good but expensive. Therefore, domestic manufacturers have transformed the production of optical transceivers to meet domestic needs.

Optical transceivers are generally used in pairs. You can understand it as a codec. The far end converts the analog signal into a digital signal, and then the digital signal is converted into an optical signal, which is transmitted through the optical fiber. The opposite is true at the center: optical signal conversion Into a digital signal, the digital signal is converted into an analog signal. The reason for using the optical transceiver is that the optical transmission distance is long and the loss is small, and the ordinary cable transmission loss is too large.

Function: It mainly uses optical transmission characteristics to achieve remote transmission through signal modulation, photoelectric conversion and other technologies.
