Comnet FVT414S1 4-Channel Digitally Encoded Video Transmitter + 4 Bi-directional Data Channels, sm, 1 Fiber
- Digital video transmission: transmits 4 real-time color video signals and 4 bi-directional data signals on one optical fiber
- Supports RS232, RS422, and 2 or 4-wire RS485 with tri-state data interfaces
- Exceptionally low video distortion with zero Performance Variation vs. Optical Path Loss
- Ideally suited to networks requiring multiple physical layers where video degradation may be a problem
- Compatible with all NTSC, PAL, or SECAM CCTV camera systems

The ComNetâ„¢ FVT414S1 video transmitter/data transceiver and video receiver/data transceiver series utilize digital encoding and decoding for high-quality 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 tristate 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. Packaged in the exclusive ComNet ComFit housing, these units may be either wall or rackmounted, or may be DIN-rail mounted by the addition of ComNet model DINBKT1 adaptor plate.
