ComNet FVR110M Fiber Optic Video Receiver Module

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The ComNet FVR110M is a rugged, industrial-grade fiber optic video receiver designed to receive a single channel of digitally encoded composite video along with bi-directional pan-tilt-zoom (PTZ) control data over a single multimode optical fiber. Optimized for harsh environments, the FVR110M is widely deployed across intelligent transportation systems (ITS), perimeter security networks, municipal surveillance grids, and industrial process monitoring facilities where electrical interference and ground loops compromise standard copper coaxial cabling.

From a total cost of ownership (TCO) perspective, securing a New Surplus ComNet FVR110M provides direct capital efficiency for facilities maintaining legacy CCTV fiber backbones. Because security systems often operate continuously under extreme temperature swings, pulled or refurbished fiber modules frequently suffer from degraded optical laser/photodiode sensitivity, leading to video signal loss or PTZ command latencies. A single video link failure at a critical intersection or industrial perimeter can trigger costly security outages and emergency dispatch calls. Installing a factory-sealed New Surplus FVR110M ensures pristine optical budget performance, preserves 8-bit video resolution, and avoids the immediate $50,000+ capital expenditure required for a complete overhaul to IP-based cameras.

Installation & Configuration Guide

1.Pre-Installation (Preparation & Safety):Disconnect power feeds and inspect fiber end-faces.

Isolate 12V DC power to the receiving station and attach a grounded ESD wrist strap before handling the hardware. Inspect the ST fiber optic patch cable connector using a fiber inspection scope to ensure the optical ferrule is free of dust, oils, or scratches. Clean with an isopropyl alcohol optical wipe if necessary.

2.Hardware Configuration & Mounting:Set data switches and mount hardware.

Configure the side-mounted DIP switches on the FVR110M to match the field camera’s PTZ data protocol (RS-232, RS-422, or RS-485 2-wire/4-wire). Secure the standalone module to the wall surface or slide it into a ComNet C1 card cage rack using the integrated mounting flanges.

3.Interface Cable Termination:Connect optical and video cables.

Connect the incoming multimode fiber cable to the ST optical port until the bayonet lock twists and clicks into position. Connect a 75-ohm BNC coaxial cable from the video output port to the monitoring display, matrix switcher, or digital video recorder (DVR). Land the 2-wire or 4-wire PTZ data leads onto the screw terminal block.

4.Power-On & Signal Verification:Verify power and optical link diagnostic LEDs.

Apply 12V DC power to the terminal strip. Observe the front panel diagnostic LEDs: confirm that the POWER LED glows solid green and the OPTICAL LINK / VIDEO DETECT LEDs illuminate to indicate adequate optical power reception. Verify live video rendering on the monitor and perform a PTZ camera sweep to validate bi-directional data flow.

Firmware/Software Versions & Upgrade Notes

The ComNet is an unmanaged hardware-level optical transceiver that processes video and serial data signals directly in hardware without operating system microcode.

• Protocol Independence: The module features transparent data encoding, making it fully compatible with major CCTV protocols including Pelco-D, Pelco-P, Bosch, Vicon, and Panasonic PTZ data formats.
• Optical Budget Alignment: Ensure that the transmitting unit (e.g., ComNet FVT110M) matches the multimode optical budget specs. Using a singlemode transmitter with a multimode receiver will result in severe optical attenuation or signal clipping.
• Hardware Replacement Note: Swapping an module requires zero software downloads or network re-addressing. Ensure DIP switch positions for data termination resistors (120-ohm RS-485 termination) match the replaced card to prevent serial data reflections on long control lines.

Frequently Asked Questions (FAQ)

Is this ComNet unit brand new or refurbished?

This product is a Brand New Surplus unit. It has never been installed in an active rack, never deployed in a field panel, and never refurbished. It comes directly from unused project inventory in original ESD-protective packaging.

What is the difference between the and singlemode versions like the FVR110S?

The is specifically engineered for multimode fiber optics (typically 62.5/125 µm or 50/125 µm core diameters) operating over distances up to 4 km. The FVR110S is designed for singlemode fiber (9/125 µm core) for long-haul runs up to 60 km. You cannot mix singlemode receivers with multimode field fiber without suffering severe optical loss.

Can the be mounted inside a rack chassis?

Yes. The features ComNet’s standard ComFit design, allowing it to function as a standalone desktop/wall-mount unit or to be slid directly into a ComNet C1 rack chassis enclosure without any hardware modification.

How do you test and verify the module prior to shipping?

Every undergoes strict quality verification. Our technicians inspect the ST optical port ferrule under magnification, test power terminal continuity, verify serial numbers, and re-seal the unit in anti-static protective packaging before shipment.

What warranty is provided with this New Surplus unit?

We back this New Surplus ComNet with a full 1-year warranty from the date of delivery. If any hardware defect or optical port issue occurs during installation or operation, we will provide an immediate replacement or issue a full refund.
