Comnet 12 Channel Video Receiver mm 1 fiber - FVR120M1

Comnet FVR120M1 12-Channel Video Receiver

Overview

The Comnet FVR120M1 is a 12-channel video receiver designed to extract analog or digitized video signals from fiber-optic transport links and convert them back to usable video outputs in a rack-mounted installation. This card-cage receiver is built for surveillance system architectures where long-distance fiber deployment separates camera clusters from central recording or monitoring hubs—typical in large industrial campuses, multi-building enterprises, or installations where copper runs are impractical or introduce EMI risk.

The FVR120M1 operates as a passive receiver in a point-to-multipoint or point-to-point fiber system, accepting 10-bit encoded video streams and regenerating them at the far end. It pairs with Comnet transmitters (such as models in the FVT series) to form complete fiber-optic video distribution chains, allowing you to place cameras or pre-processed video sources hundreds of meters away without signal degradation or the bandwidth limits of unshielded copper runs.

Key Features

• 12 Video Channels: Handles up to 12 discrete video streams on a single fiber connection, reducing the need for multiple fiber pairs or copper bundles. Consolidating this many channels onto one strand simplifies routing, reduces conduit congestion, and cuts installation labor compared to running separate cables per channel.
• 10-bit Video Encoding: Processes 10-bit encoded video data, preserving color depth and tonal gradation across the transmission chain. This matters if your source cameras or analog-to-digital converters produce 10-bit streams—you avoid quantization loss that would occur with 8-bit conversion, keeping forensic-grade detail intact.
• Single Fiber Architecture: All 12 channels multiplex over one fiber strand, dramatically cutting installation cost and complexity in long-run deployments. A typical 500-meter fiber run to a remote warehouse or rooftop repeater becomes a single cable pull instead of a dozen copper runs or multiple fiber pairs.
• Card-Cage Rack Mount Form Factor: Installed in a standard 19-inch rack chassis, the FVR120M1 integrates into existing NOC or equipment room layouts without requiring separate wall-mount hardware or floor space. Vertical stacking of multiple receiver cards in a single chassis accommodates multi-site or multi-zone video consolidation.
• ComNet C1PS Power Supply Compatibility: Operates from ComNet's standard C1PS power supply module, ensuring consistent architecture across your fiber-optic video transport infrastructure. Standardized power input simplifies redundancy planning and spare parts procurement.
• Passive Receive Operation: Functions as a transparent video receiver with no active signal processing or frame loss between input and output. Raw video fidelity is preserved, leaving analytics and recording decisions to downstream VMS or DVR systems.

Integration and Compatibility

The FVR120M1 is the receiving endpoint in a Comnet fiber-optic video transport system. It expects video input from a compatible Comnet transmitter card (such as the FVT120M1 or equivalent multi-channel transmitter) operating over single-mode or multi-mode fiber.

Video outputs from the receiver feed standard analog or digital video inputs on surveillance DVRs, NVRs, video matrices, or distribution amplifiers. No proprietary software, ONVIF negotiation, or IP network configuration is required—it is a hardware-level converter that regenerates video signals at the far end of a fiber run.

Deployment contexts include remote camera clusters in multi-building campuses, fiber-fed repeater stations for extended range, and long-distance video transport in environments where fiber offers immunity from electrical noise. Industrial facilities with high RF interference, power distribution substations, or outdoor installations spanning 1+ km benefit most from this architecture.

Frequently Asked Questions

Q: What type of fiber does the FVR120M1 support—single-mode or multi-mode?

A: Comnet fiber video systems typically support both single-mode and multi-mode fiber depending on the transmitter paired with this receiver. Confirm fiber type with your transmitter model specification and channel distance requirements. Single-mode enables longer runs (up to 10+ km); multi-mode is suitable for shorter campus deployments (up to 2 km).

Q: Does the FVR120M1 require synchronization with the transmitter, or does it work with any Comnet transmitter?

A: The receiver must pair with a compatible Comnet transmitter operating on the same fiber link. Synchronization occurs at the optical transport layer; no external clock or trigger input is needed. Confirm transmitter model compatibility with your system design.

Q: What is the maximum distance the FVR120M1 can receive video over fiber?

A: Distance capability depends on fiber type, transmitter power, and receiver sensitivity. Single-mode fiber typically supports 10–20 km; multi-mode supports 2–5 km. Consult the specific transmitter datasheet for distance ratings and optical power budgets.

Q: Can I use the FVR120M1 to extend video from legacy analog cameras?

A: Yes, if paired with a compatible Comnet transmitter that accepts analog video inputs. The transmitter encodes analog video, transmits it over fiber, and the FVR120M1 recovers it at the far end as analog output—no intermediary digitization or IP conversion required.

Q: What power supply do I need, and what is the typical power draw?

A: The FVR120M1 operates from the Comnet C1PS power supply module. Exact current draw is not specified in available documentation; contact Comnet or your distributor for power consumption and redundancy power supply options.

Q: Is the FVR120M1 suitable for outdoor or high-EMI environments?

A: Fiber-optic systems are inherently immune to electromagnetic interference and RF noise. The FVR120M1 receiver itself is typically housed in a climate-controlled rack; if deploying in outdoor conditions, place it in a weatherproof equipment cabinet or enclosure and ensure proper grounding on the fiber distribution panel.

The FVR120M1 solves a specific problem: you have cameras or video sources at distance—maybe a remote warehouse, a substation, or a distributed campus—and running 12 or more copper video lines over hundreds of meters isn't practical. Fiber kills two birds: distance and noise immunity. The 10-bit encoding on the FVR120M1 preserves tonal detail across the fiber run, so when your video emerges at the rack end, it hasn't been compressed or degraded by the journey.

Technical Highlights:

• 10-bit Video Encoding: Maintains 10-bit color depth and tonal gradation end-to-end. Compared to 8-bit systems, you retain an extra 4x color information per pixel—critical if your forensic or analytics workflow depends on subtle shadow or highlight detail. Quantization artifacts disappear.
• 12 Channels on 1 Fiber: All 12 video feeds multiplex over a single fiber strand. This cuts fiber runs from 12 separate cables (or 6 pairs for redundancy) to one, eliminating conduit bottlenecks and reducing install time by weeks in large campus deployments. Economics matter: fewer splices, fewer termination points, lower failure surface.
• Card-Cage Rack Mount: Slots into a 19-inch chassis—no field wiring, no separate enclosure. Vertical integration means you can stack multiple FVR120M1 receivers in one rack if you're consolidating video from multiple fiber rings. Cooling and power come from the shared chassis.

Deployment Considerations:

• The FVR120M1 is a slave device—it must be paired with a compatible Comnet transmitter on the far end. Verify transmitter model and fiber type (single-mode vs. multi-mode) before you buy; mixing incompatible transmitters and receivers wastes money and installation time.
• Power is supplied via the C1PS module, which is not included with all chassis. Confirm your rack power budget and whether C1PS is already installed or a separate procurement. A redundancy supply (dual C1PS setup) is common in critical surveillance hubs but requires explicit design.

This receiver is the right fit for industrial or enterprise multi-site surveillance where fiber backbone economics win—think oil refinery camera clusters, pharmaceutical campus networks, or power distribution networks spanning 10+ km. If your deployment is a single building with copper runs under 200 feet, you're paying for capability you don't need. But if fiber is already in the ground or EMI is a known problem, the FVR120M1 earns its place in the architecture.
