Optical Video/Audio Transmission Systems (WT-V400-4V)

Product Description

WT-V400-4V Series: Digitized 4 Channels Video Over Fiber
WT-V400-4V series products provide transmission of 4 channels video, 4 channels bi-directional audio, control data and 1 channel 10M/100M Ethernet over a single optical fiber. The product utilizes 8-bit encoding for video transmission without any distortion. Completely compatible with NTSC, PAL and SECAM CCTV video system, the product's video specifications exceed the requirements of EIA RS-250C Medium-Haul standards. Flexible data interfaces are supported including RS232, RS422/RS485, TTL signal or Contact-Closure signal. Plug-and-play design ensures ease of installation and free of electrical or optical adjustments. LED indicators are also provided for rapidly system diagnosis. Our robust design ensures extremely high reliability in any Out-of-Plant installations.
