Comnet Comfit 10/100MBPS Commercial Grade Enet TO Copper OR Coax - CNFE1EOC

Comnet CNFE1EOC Ethernet to Copper/Coax Converter

The Comnet CNFE1EOC is a commercial-grade Ethernet-to-copper or coax converter built for surveillance networks where existing coaxial or twisted-pair cabling already runs through walls and conduit. Instead of rewiring a building, this device lets you extend IP camera feeds and data over legacy copper infrastructure, delivering 10/100 Mbps Ethernet performance across distances up to 100 meters (328 feet) per run.

Key Features

• 10/100 Mbps Ethernet bridging: Delivers full duplex data at 90 Mbps throughput — fast enough for H.264 or H.265 video streams and network traffic without bottleneck. Standard IEEE 802.3 compliance ensures compatibility with any managed or unmanaged Ethernet source.
• 100-meter span on copper or coax: Covers the length of most commercial buildings or warehouse runs on a single line card. Eliminates the need for mid-span repeaters or additional infrastructure in retrofit scenarios where coax ducts are already in place.
• Dual transmission options: Works with either unshielded twisted-pair copper cabling or existing coaxial runs — choose the medium that matches your in-wall routing. Single card solution reduces enclosure footprint and simplifies field deployment.
• Low power draw (9–12 VDC @ 1A): Runs on standard 12V DC supplies found in most surveillance power distribution systems. Single amp requirement keeps it off the main power budget for camera racks or remote cabinets.
• Screw-terminal wiring (No. 6 pan head): Uses field-standard 3mm or 3.55mm fasteners for quick panel-mount or DIN-rail installation. No custom connectors or proprietary interfaces — typical commercial-grade integration.
• Commercial-grade design: Built for protected indoor (dry) locations in control rooms, base stations, or head-end shelters. Approved for environments where temperature and humidity are controlled — not rated for outdoor or harsh-condition cabinets.

Integration & Compatibility

The CNFE1EOC pairs with any standards-based Ethernet source — IP cameras, network switches, VMS servers, or edge recorders that output 10/100 Mbps. The converter bridges the physical layer, so it works transparently with H.264, H.265, MJPEG, or raw data traffic without codec awareness. In retrofit installations, it eliminates the cost and labor of pulling new Cat5/Cat6 when coax or twisted-pair is already present in the structure. Typical deployment: camera head-end to a remote base station or distributed recording node across existing building cabling.

What's in the Box

The CNFE1EOC ships as a standalone converter module. Verify your installation includes appropriate 9–12 VDC power supply, Ethernet patch cables (not included), and copper or coax jumpers matched to your cabling plant. Screw-terminal connections require a standard Phillips or flathead screwdriver.

Frequently Asked Questions

Q: Can the CNFE1EOC run over existing RG-6 or RG-59 coaxial cable?

A: Yes. The converter accepts either unshielded twisted-pair copper or coaxial media. Coax runs are common in legacy CCTV plants; the CNFE1EOC bridges Ethernet over that same infrastructure, extending your IP camera reach without new conduit pulls.

Q: What happens if I exceed the 100-meter distance?

A: Performance degrades beyond 100 meters due to copper loss and capacitance. Plan for one converter per 100m span. If your run is longer, stage multiple converters with a hub or switch in the middle to maintain throughput.

Q: Is the CNFE1EOC suitable for outdoor or wet locations?

A: No. It is designed for protected dry environments (control rooms, equipment racks, shelters). Do not expose to direct rain, condensation, or temperature swings beyond standard HVAC ranges. For outdoor base stations, house it in an enclosure with climate control.

Q: What power supply do I need?

A: Any regulated 9–12 VDC supply rated for at least 1 amp. Standard industrial/security switching supplies (12V 2A or 5A) are overkill but work fine. Screw terminals accept 14 AWG or smaller wire.

Q: Does the CNFE1EOC support PoE passthrough?

A: No. It is a Layer 1/2 bridge with no PoE injection or extraction. If your far-end device needs PoE, use a separate PoE injector or midspan unit on the Ethernet side.

Q: Can I daisy-chain multiple CNFE1EOC units?

A: Yes, as long as each span does not exceed 100 meters. Use a managed or unmanaged Ethernet switch at intermediate points to re-power and bridge signals across multiple runs.

The CNFE1EOC solves a specific pain point in surveillance retrofit work: you've got legacy coax runs already in the walls, but your new IP cameras and recorders speak Ethernet. Rather than tear out drywall to run Cat6, this converter stretches IP traffic over that existing copper at 90 Mbps — exactly what most H.264 camera streams need.

Technical Highlights:

• 90 Mbps throughput at 100m span: Enough headroom for multiple H.264 or H.265 camera feeds without queueing. At 100 meters you lose some signal margin, but the 10/100 negotiation is transparent — the converter just moves data.
• 9–12 VDC @ 1A power: Minimal draw means you can run it off the same 12V supply rack that feeds your outdoor PoE switches. No separate power infrastructure, no 24VAC transformer — just a barrel jack or screw terminals.
• Dual-media flexibility (copper or coax): Not locked to one cabling type. If your building routed RG-6 for old analog, this converter uses it. If you've got spare twisted-pair in the same conduit, use that instead. Field crews appreciate not having to argue about cable plant.

Deployment Considerations:

• Dry indoor only — enclosure, temperature, humidity control mandatory. If you're installing in an unheated warehouse or rooftop hutch, the CNFE1EOC will fail or drift out of spec quickly.
• 100m is a hard limit. At that distance, capacitive loss and impedance mismatch start to bite. If your run is 150m, you need a switch or hub in the middle to regenerate the signal — plan for that cost upfront.
• No PoE injection. If your far-end IP camera needs power, you must run a separate 12V line or install a PoE midspan on the Ethernet side. The converter is passive Layer 1 — it does not synthesize power.

Best fit: building-scale retrofit where coax is already in place and you're migrating from analog CCTV to IP over existing infrastructure. Worst fit: greenfield installations where you can run new fiber or Cat6 — you'll spend less time troubleshooting impedance and distance limits.
