Comnet FVT4014M1 4 Channel Digitally Encoded Video Transmitter + 4 Channels Bi-directional Data Channels, 1 Fiber, Multimode

The ComNet™ FVT/FVR4014 video transmitter/data transceiver and video receiver/data transceiver series utilize 10-bit digital encoding and decoding for high-quality video transmission that meets the requirements of EIA RS-250C for short-haul video transmission. These environmentally hardened units provide transmission of four independent video channels and four bi-directional data channels over one optical fiber and are ideal for use in unconditioned roadside or out-of-plant installations. These units are completely transparent to and universally compatible with any NTSC, PAL, or SECAM CCTV camera systems, data channels can be set independently for RS232, RS422 and 2 or 4-wire RS485 with tri-state support. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required. Bi-color (Red/Green) LED indicators are provided for rapidly ascertaining equipment operating status. These units are interchangeable between stand-alone or card mount configurations.

Features

10-bit digital video transmission: transmits 2 real-time color video signals and 4 bi-directional data signals on one optical fiber

Video Receiver/Data Transceiver (1550/1310 nm)
