Optical fiber transmission facilitates the development of high-definition surveillance

The application range of optical fiber transmission is quite extensive, which can be roughly divided into five categories
such as telecommunication networks.
In the monitoring network, there are also ways
to convert digital image signals into optical TCP/IP signals through TCP/IP networks for transmission and restoration.

Due to the rapid development of optical fiber transmission technology, the cost of optical fiber transmission monitoring system has been greatly reduced, so the application of optical fiber and optical transceiver in monitoring system is becoming more and more popular
.
Optical fiber transmission has five advantages: frequency bandwidth, large communication; Low loss and long transmission distance; Light weight, small size, easy to lay and transport; Anti-electromagnetic interference, no crosstalk interference, high confidentiality; Fiber optic cables are adaptable and have a long
life.

The potential bandwidth of an optical fiber can reach 20THz, and the transmission distance without relay can reach tens of kilometers, using such a bandwidth, it only takes about a second to transmit all the written data of human beings, ancient and modern
, Chinese and foreign.
Electrical communication has never been able to solve various electromagnetic interference problems, only optical fiber transmission is not subject to various electromagnetic interference
.
Therefore, optical fiber has become the preferred transmission medium
for transmitting digital high-definition signals.

With the increasing number of various image status and data monitoring requirements, the image signal transmission distance can no longer meet the demand, so the gradual development of optical fiber integration of image and control signals, which can transmit longer distances
.
In addition to the requirements of combining image and control, the architecture of optical fiber monitoring transmission is the main axis of the entire optical fiber transmission construction, and with different deployment methods, there will be different uses and functions
.

Optical fiber transmission mainly relies on the optical transceiver to convert one end of the optical fiber into an optical signal, and at the other end to convert the optical signal back to the corresponding electrical signal
.
With the development of optical fiber communication technology, there are more and more ways of image transmission, and the video signal transmission of optical transceiver has greater advantages
than other such as twisted pair transmission and coaxial cable transmission.
