Fiber Optic Transmission Multipoint-to-Point Solution

The theory of multipoint-to-point and point-to-point transmission form is basically same. But receivers of multipoint-to-point all use rack-mount, the receivers are card style and inserted into chassis. That is transmitters are stand-alone, receivers are rack-mount, must use in pairs, for example, 4-channel stand-alone transmitters must connect with 4-channel rack-mount receivers.
This transmission form advantage is to facilitate the back-end management, centralized power supply, and can be installed in standard 19-inch rack, also could choose network management system that could better monitor working state for convenient maintenance and management of fiber optic transmitters and receivers.

In the above case is the system separately composed of 1-channel, 2-channel, 4-channel and 8-channel fiber video optic transmitter and receiver.
In the front-end video signal collected by fixed or PTZ cameras, and then the video electronic signal is converted into optical signal by 1-channel, 2-channel, 4-channel and 8-channel transmitters, also transmit the optical signal to relevant card style receivers (insert into chassis) by means of single-mode or multi-mode optical cable. then receivers convert optical signal into video signal output to DVR or matrix etc.
Camera’s video images finally transmitted to indicator, meanwhile, users could control PTZ cameras by keyboard. In the whole transmission process fully use digital transmission, image lossless, uncompressed, No EMI or RFI, images collected by cameras could clearly transmit to indicator.
