The 28-Channel Single-Mode 10-Bit Digital Video Receiver/Data Transceiver from ComNet utilizes 10-bit digital encoding and decoding for high-quality video transmission that meets the requirements of EIA RS-250C short-haul video transmission. It receives 28 real-time/full frame color video signals and 8 bi-directional data signals over one single-mode optical fiber. This unit is universally compatible with any NTSC, PAL, or SECAM CCTV camera systems. The data channels can be set independently for RS232, RS422 and 2 or 4-wire RS485, Sensornet, Bi-phase, and Manchester. The environmentally hardened receiver unit is suitable for use in unconditioned roadside or out-of-plant installations. Its plug-and-play design ensures ease of installation with no electrical or optical adjustments required.

Compatible with
All NTSC, PAL, or SECAM CCTV camera systems
10-bit digital video transmission—receives 28 real-time/full frame color video signals and 8 bi-directional data signals on one optical fiber
Maximum transmission distance up to 22 mi (36 km)
High video performance—meets the requirements of EIA RS-250C short-haul transmission
Low video distortion with zero performance variation verses optical path loss
Complies with the environmental requirements of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment, such as ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection
Voltage transient protection on all power and signal input/output lines provides unconditional protection from power surges and other voltage transient events
Robust design ensures high reliability in unconditioned out-of-plant environments
Bi-color (red/green) LED status indicators provide rapid indication of critical operating parameters
Suitable for high-performance CCTV applications
