Summary： 

 ZB-V series of small digital video optical transceiver can achieve 4 high quality digital video, 1 ~ 2 and 1 ~ 3 two-way audio bidirectional asynchronous data or 1 ~ 2 high quality digital video, 1 ~ 2, 1 ~ 3 two-way audio bidirectional asynchronous data and 1 10/100M self adaptation the Ethernet data in the 1 core fiber on high quality real-time transmission. 
 This series of products with good price, is the best products to replace the traditional small capacity PFM analog optical transceiver, and more stable performance, superior technical index. 
 The signal transmission loss is low, the transmission distance is far, the television signal has the very wide frequency band, the long-distance transmission is very difficult. Optical fiber transmission of video signals, transmission bandwidth of up to several hundred million kilometers. It can ensure that the long-distance transmission has a high signal to noise ratio, without the need of high frequency compensation. This is the conventional cable can not be compared. 
 Anti interference is strong, no electromagnetic radiation, no signal leakage, no grounding and short circuit problems, the system power consumption is small. 
 - became widely used in a large number of video, electronic police, highway, traffic monitoring, security, industrial automation, electric power, water conservancy, customs, banking and other areas of image, audio, data, telephone, Ethernet optical transceiver. The early analog FM transmitter, amplitude and phase occupies a considerable proportion in the market, now because the digital video fibertransmissionsystem falling prices and its advantages, in a variety of applications in analog optical transceiver has been gradually replaced.
