Comnet 8-Channel Digitally Encoded Video Receiver + 2 Bi-directional Data Channels - FVR80D2SFP

Comnet FVR80D2SFP 8-Channel Digital Video Receiver

The Comnet FVR80D2SFP is an 8-channel digitally encoded video receiver designed to recover CCTV signals transmitted over fiber-optic links. Purpose-built for long-distance, noise-immune video distribution in industrial and transportation environments, the FVR80D2SFP handles up to eight 10-bit digital video channels, two bi-directional data channels, and one bi-directional contact closure channel — all through a single, hot-swappable small form factor pluggable (SFP) module. This architecture eliminates the need for separate power supplies or external adjustments, making it a straightforward drop-in receiver for distributed surveillance architectures where copper runs would be impractical or electrically risky.

Key Features

• 8 × 10-bit Digital Video Channels: Receives digitally encoded CCTV signals at short-haul RS-250C quality, preserving forensic-grade clarity across fiber runs without the electrical noise penalties of analog coax. Each channel operates independently, so you can mix and match NTSC, PAL, or SECAM sources on a single receiver.
• 2 Bi-directional Data Channels: RS232, RS422, 2-wire, and 4-wire RS485 support means you can backhaul PTZ control, alarm data, or sensor telemetry alongside video without extra conduit or twisted-pair runs. Reduces installation cost on long-distance deployments (parking lots, toll plazas, highway corridors).
• 1 Contact Closure Channel (Bi-directional): Relay control for triggering gate locks, alarm indicators, or lighting circuits. Useful for coordinating access control or incident response across distant camera sites.
• Interchangeable SFP Modules: The receiver accepts SFPs matched to your fiber type (single-mode, multimode) and distance budget — no proprietary lock-in. You can upgrade transmission distance or switch fiber type without replacing the entire chassis. This flexibility is critical in expanding surveillance networks without wholesale equipment replacement.
• NEMA TS-2 Environmental Rating: Designed for outdoor, unheated cabinets and roadside installations. The -40°C to +75°C operating range covers desert heat and subzero winters without derating performance — meaning reliability in toll booths, railway sidings, and remote traffic signal cabinets where HVAC control is impossible.
• Voltage Transient Protection: All power and signal lines include surge suppression, protecting against lightning strikes and grid switching transients common in industrial settings. Reduces warranty claims and unplanned downtime on long-distance routes.
• Hot-Swappable Rack Modules & ComFit Design: The FVR80D2SFP works stand-alone or in standard 19-inch racks and accepts Comnet's ComFit mounting scheme, letting you deploy the same hardware in terminal cabinets, control rooms, or roadside enclosures without re-engineering brackets.
• Bi-color LED Status Indicators: Green/amber/red feedback on power, video sync, and fiber link health — no network access required to verify signal health. On-site technicians can diagnose problems in seconds without opening a VMS.
• Lifetime Warranty & Made in USA: Backed by a lifetime manufacturer warranty and built domestically, reducing supply-chain risk for critical transportation and industrial surveillance projects.

Integration & Compatibility

The FVR80D2SFP pairs with Comnet's FVT80D2SFP transmitter or any compatible fiber-optic transmitter supporting the same SFP type and distance rating. Plug-and-play design requires no electrical or optical adjustments — fiber connection and power are the only setup steps. Compatible with standard CCTV infrastructure (DVRs, matrix switchers, analog VMS systems) at the receiver outputs, and with any access control or PLC that supports RS485, RS232, or dry-contact relay logic via the data and contact closure channels. If you are building a network video recorder architecture, the FVR80D2SFP converts fiber-transmitted analog video back to baseband for older DVR ports; newer deployments often pair these with video servers or edge NVRs at the remote site to keep data local and minimize latency.

Frequently Asked Questions

Q: What is the maximum fiber transmission distance for the FVR80D2SFP?

A: Distance depends on the SFP module installed. The receiver itself is distance-agnostic — the SFP determines the fiber type (single-mode for 20+ km, multimode for shorter runs) and connector type. Consult your SFP datasheet or contact pre-sales engineering for distance/fiber matching to your site layout.

Q: Can the FVR80D2SFP work with both analog NTSC and PAL cameras at the same time?

A: Yes. Each of the eight video channels is independent and can receive NTSC, PAL, or SECAM signal. This is useful on international projects or multi-standard facilities where camera sources vary by zone.

Q: Does the FVR80D2SFP require any external power supply beyond what's on the unit?

A: No. The receiver has integrated power on a standard 24VDC input. No external PSU is required beyond the site's main power panel.

Q: What happens if the fiber link is interrupted?

A: The LED indicators will show link loss (red). Video and data channels will drop until the fiber connection is restored. There is no automatic failover; redundancy (dual fiber runs or secondary receivers) must be designed into the system architecture.

Q: Is the FVR80D2SFP compatible with Comnet transmitters only?

A: The FVR80D2SFP is designed to pair with Comnet's FVT80D2SFP transmitter or other compatible fiber encoders that support the same SFP interface and digital encoding standard. Verify SFP type and encoding protocol before purchasing.

Q: What is the warranty period?

A: The FVR80D2SFP is backed by a lifetime manufacturer warranty, covering defects in materials and workmanship for the life of the device.

James Everett

The Comnet FVR80D2SFP is a specialized long-haul video receiver — not a general-purpose unit. Its strength lies in recovering digitally encoded video across fiber without the latency, bandwidth, or noise issues that plague analog coax over extended runs. If you're deploying cameras 5+ kilometers from a control facility or running links through electromagnetically hostile environments (railroad yards, power substations, toll plazas), this receiver is purpose-built to solve that problem.

Technical Highlights:

• 8-Channel 10-bit Digital Video: Each channel recovers digitally encoded CCTV at RS-250C short-haul spec — meaning forensic-quality full-motion video without drift or signal degradation over distance. A single fiber pair can carry all eight channels, eliminating eight separate analog coax runs.
• NEMA TS-2 & -40°C to +75°C Rating: Built for unheated, outdoor industrial cabinets. You don't need to spec HVAC or insulated enclosures just to keep this receiver operational — it's hardened for roadside, rural, and extreme-temperature environments where standard commercial electronics would fail.
• Interchangeable SFP Modules: The modular SFP design means you upgrade transmission distance (single-mode vs. multimode) or swap fiber connectors without replacing the whole chassis. On multi-year, multi-site deployments, this modularity saves thousands in swap-out labor and spares management.

Deployment Considerations:

• The FVR80D2SFP is a receiver only — you must pair it with a compatible fiber transmitter (like the Comnet FVT80D2SFP) at the camera/video source end. If you don't already have a transmitter in place, that's a second capital line item and installation cost.
• Fiber-optic systems require trained installers for termination and testing — this is not plug-and-play in the way IP cameras are. Budget for fiber splicing, power meter verification, and continuity testing before declaring a run live.
• No automatic failover or redundancy is built in — if the fiber link breaks, video and data stop cold. Critical deployments require dual fiber runs and secondary receivers, which doubles fiber infrastructure cost.

Deploy the FVR80D2SFP on long-distance surveillance systems serving highway corridors, rail yards, pipeline monitoring, or remote utility substations where fiber immunity to electrical noise and distance capability outweigh the added installation complexity and cost of fiber infrastructure.
