Comnet FVTR1A2D1C1M1A Bi-directional Fiber Transceiver
Overview
The FVTR1A2D1C1M1A is a bi-directional video, audio, data, and contact closure transceiver designed to extend analog video surveillance systems over multimode fiber up to 30 miles. This module solves the distance and interference problem when running analog CCTV, intercom, and control signals across campus installations, between buildings, or to remote monitoring sites where copper runs become impractical. The 10-bit video channel carries full-resolution analog signal; the two bi-directional audio channels (20Hz–18kHz, 600 Ohm impedance, +6dBm output) support two-way voice or intercom; and the RS-232/422/485 data interface manages DVR/NVR control, PTZ commands, or alarm relay logic. One bi-directional contact closure handles door locks, gate triggers, or alarm panel inputs.
Compatibility
Install the FVTR1A2D1C1M1A at both ends of a fiber run—one at the camera/source location and one at the control room or recorder. Compatible with any analog video system (CCTV cameras, hybrid DVRs, analog matrix switchers) that outputs composite or distributed audio and accepts RS-232/422/485 serial commands. Multimode ST connectors mate directly to standard telecom fiber infrastructure, making this a fit for existing campus fiber networks, dark fiber leases, or commercial telecommunications runs. No single-mode conversion needed.
Installation Notes
Mount on a 19-inch rack or surface-mount in an equipment enclosure. Operating temperature range is NEMA TS-1/TS-2 (typically –10°C to +60°C depending on installation). Transient voltage protection safeguards against lightning strikes on long outdoor fiber runs. Verify fiber continuity and loss at installation; modal dispersion limits on multimode fiber do not affect 30-mile analog video transmission at standard bandwidth. Pair units as transmitter and receiver (one direction per unit, or use two units for bi-directional): the FVTR1A2D1C1M1A designation indicates one fully bi-directional transceiver that handles all channels in both directions on a single fiber pair.
