Comnet Bi-directional Video Receiver + 2 Bi-directional Audio Channels + - FVTR1A2D1C1S1B

Comnet FVTR1A2D1C1S1B Video/Audio/Data/Contact Transceiver

Overview

The FVTR1A2D1C1S1B is a single-mode fiber transceiver that consolidates analog video, bidirectional audio, serial data (RS232/RS422/RS485), and relay/contact control into one device over distances up to 30 miles. This is a remote endpoint — pairs with a matching transmitter on the opposite fiber end. Deploy where extended-distance surveillance requires full-duplex audio conversation, command/control signaling, or alarm contact status across fiber backbone infrastructure without separate cable runs.

Compatibility

Works with any Comnet transmitter unit designed for the FVTR series. Accepts analog composite video (NTSC/PAL/SECAM) and sends/receives audio on balanced or unbalanced inputs. Serial data interface handles industrial RS232, RS422, or RS485 protocols — compatible with access control panels, DVR serial commands, and sensor/relay logic circuits. Fiber connection is 9/125µm single-mode; verify your transmitter side also specifies single-mode (not multimode) to avoid optical mismatch.

Installation Notes

Operating range is -40°F to 167°F; suitable for outdoor cabinet and underground conduit deployments. Unit dimensions: 5.30 in (W) × 2.20 in (H) × 6.10 in (D) — fits standard 1RU or compact wall enclosures. Single-mode fiber coupling requires precision LC or SC connectors; use only single-mode patch cable rated for outdoor direct-buried or conduit runs. Audio input impedance is 600 ohms — source your audio from a line-level output or mic preamp with matching impedance to avoid level loss. Data rate on serial channels depends on your protocol (typically up to 115.2 kbps); longer fiber runs may require handshake verification for RS485 chains. Maximum audio output is +6 dBm; confirm downstream amplifiers or speakers can accept that level without clipping.
