The IFS VT4930WDM video transmitter/data transceiver unit utilizes frequency modulation for high video transmission quality. These environmentally hardened units provide the simultaneous transmission of video and full-duplex data over one singlemode optical fiber and are ideal for use in unconditioned out-of-plant or roadside installations. Completely transparent to and universally compatible with any NTSC, PAL, or SECAM CCTV camera system, all standard pan-tilt-zoom control signals including RS-232, RS-422, and 2-wire RS-485 data are supported. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required. LED indicators are provided for rapidly ascertaining equipment operating status. This is the rack mount version.
