FAMC-FSDU13S-20 , 100M UART Fiber Media Converter With DB9 Port RS232 Asynchronous Optical Modem


At present, the transmission medium used to transmit image signals in monitoring system mainly has three kinds of media: coaxial cable, twisted pairs and optical fiber. The three transmission media are different, each has its own advantages and disadvantages. Among them, the optical fiber is with far transmission distance, high speed, large bandwidth, it is most suitable for long distance transmission.

Compared with coaxial cable, optical fiber has obvious advantages. Optical fiber has the advantages of high transmission distance, high speed, large bandwidth, small attenuation, and best anti-jamming performance. It is suitable for long-distance and large video transmission, such as road intersection monitoring. The farthest can even reach more than one hundred kilometers, it converts video and control signal to be optical signal and transmits in optical fiber.

Compared with optical fiber, coaxial cable is not without advantage, coaxial cable is with lower cost and more convenient for laying. Therefore, in small range of monitoring system, since the transmission distance is very close, the coaxial cable can directly transmit the monitoring image, which has little damage to the image quality, and can meet the actual requirements. However, according to the analysis of coaxial cable, when the signal is transmitted in coaxial cable, the attenuation is related to the transmission distance and the signal frequency. Generally speaking, the higher the signal frequency is, the greater the attenuation is.

In addition, compared to coaxial cable, transmission distance of twisted pair is much longer, the maximum can reach 2400 meters. Twisted pair is cheap and easy to access, and has good anti-interference ability. But the material of twisted pair is with poor anti-aging ability, and can only transmit one image at one time. It is more suitable for short distance and relatively concentrated environment, such as camera point is relatively dispersed, not many or relatively closed.

Therefore, optical fiber is the best choice for long distance transmission. Optical fiber transmission equipment mainly includes video optical transceiver and fiber media converter, video optical transceiver is mainly used in signal transmission of analog video camera, its signal loss is small, with smaller noise and distortion, high transmission quality and suitable for long distance transmission. Fiber optic media converter is suitable for signal transmission of network camera, it also has the advantages of far transmission distance, low loss, strong anti-interference ability etc.. Using optical fiber switch, PoE technology can also be used to power the front camera, reducing the work amount of integrated cabling.
