How to install fiber optic video surveillance?
How to install optical fiber video surveillance? In the video surveillance system, the use of optical fiber transmission is generally far away, and the distance of more than 100m can be used for optical fiber transmission. The optical fiber transmission has the following features: wide frequency band, low attenuation, strong anti-interference, transmission It has the characteristics of high confidentiality, and briefly introduces how to use optical fiber to transmit video surveillance.
1. How does optical fiber transmit video signals?
In the long-distance video surveillance transmission process, the optical fiber transmission method is generally used. The optical fiber transmits signals in the form of optical pulses. Use the network cable to transmit to the terminal receiving device. The material of optical fiber is mainly glass or plexiglass, which is composed of fiber core, cladding and protective sheath. Optical fiber can generally be divided into single-mode fiber and multi-mode fiber. Single-mode optical fiber transceiver: the transmission distance is 20-120 kilometers; multi-mode optical fiber transceiver: the transmission distance is 2-5 kilometers. In the monitoring and installation process, single-mode optical fiber transceivers are mostly used, with long transmission distance, stable effect, and wiring. Convenience.
2. Introduction of optical fiber transceiver transmission
Optical fiber transceivers generally only transmit 802.3 standard network signals. The main chip is a network switch chip. The receiving and sending ends need to be paired to use A and B. They can also be used with switch optical ports, matching standards. The models at both ends are -T and -R, same port rate, same suffix (-A/-B)
When the transceiver is used,
Different indicators of transceivers represent different meanings. Taking common 100M single-mode transceivers as an example, TX and FX represent the optical port mode. If they are always on, it means that the network is working in 100M mode. If it is off, it means the network is working at 10M. Mode, link is the pigtail transmission indicator, normally on means the connection is normal, if it flashes, it means that the data is being transmitted normally, act means the network cable indicator, when it is normally on, it means the network is connected, when it flashes, the network cable data transmission is normal, FDX means the electrical port half-duplex, In full duplex mode, PWR is the power indicator.
