Opvision OPV 2000

OPV2000 SERIES (Analog Video/Audio)

1-2 Channel Video/Audio/Data/Ethernet Fiber Optic Transmission System

OPV2000 series of products provide high quality digitalized transmission for 1-2 channels of analog video and 2 audio signals over one single mode or multimode fiber. Normally, all the transmission is in the same direction, while expanded OPV2000 products can be bi-directional.

OPV2000 system, with the aid of OPV6000 leading to OPV2060, can at most transmit 2 channels of video, 4 audio (two pairs of stereos), 2 RS-232 and 2 RS-485 signals, and 2 ports of 10/100M Ethernet. The transmission distance is up to 2 Km for multimode fiber and 30 Km for single mode fiber. Compared to the traditional analog transmission system that employs random amplitude or frequency modulation, OPV2000 provides better transmission in quality due to the advanced digital technology.

OPV2000 devices can be installed rapidly without user adjustment, and can be operated and maintained readily. Users can easily monitor the status of power supply, connection and channel operation through the indicator lights on the front panel. Two versions of OPV2000 are available for options: standalone and card-cage.
