Comnet Local Four-Channel Ethernet-over-UTP Extender With 30W PSE PoE+ - CLLFE4POEU

Comnet CLLFE4POEU Four-Channel Ethernet-over-UTP Extender With PoE+

Overview

The Comnet CLLFE4POEU is a four-channel Ethernet-over-copper extender that solves a real problem: extending powered IP cameras, access control readers, and network devices far beyond standard PoE switch reach. It injects or passes through full 802.3at PoE+ power (30W total) over existing UTP cable—CAT-5 twisted pair or coaxial—letting you retrofit CCTV infrastructure without pulling new fiber or licensed conduit. Designed and manufactured in the USA, it handles transmission distances up to 3,000 feet over UTP at 10 Mbps, or 2,000 feet at full 100 Mbps bandwidth. This is the model to reach distant parking lots, rooftops, or warehouse wings where traditional switch placement isn't practical.

Key Features

• 30W PoE+ Power Injection: Supports IEEE 802.3at PoE+ with 48–56V input voltage, delivering enough current for high-drain cameras, pan-tilt-zoom units, and multi-sensor systems. No separate power supplies needed at remote locations if you're using PoE+ injection mode.
• Extended Distance over Standard Copper: Reaches 3,000 feet (914 m) at 10 Mbps or 2,000 feet (610 m) at 100 Mbps over UTP cable—meaningful when your network switch or PoE+ injector is in a central location and your camera or access control reader is across a large campus or warehouse. Coax reach extends to 5,000 feet at 10 Mbps.
• Four Independent Channels: Each channel carries full 10/100 Mbps Ethernet data independently, so you're not splitting bandwidth across devices—a 100 Mbps camera on channel 1 doesn't slow down a 100 Mbps access reader on channel 2.
• Pass-Through or Injection Mode: Wire it as a Local module generating power (with external 48–56V supply) or as a Remote end passing PoE+ from a compliant switch upstream. Flexible topology for retrofit or new builds where generator or 24V DC power is available on-site.
• Full Bandwidth Symmetry: Supports TCP/IP, UDP, HTTP/HTTPS, and multicast traffic with virtually zero packet loss over the rated distance. RFC 2544 tested for throughput guarantees—not best-effort over long copper runs.
• NEMA TS-1/TS-2 Traffic Signal Compliance: Type-tested and independently certified for ambient temperature swings (-40°C to +75°C), mechanical shock, vibration, humidity (0–95% non-condensing), and transient voltage protection. Built to outlast harsh outdoor or uncontrolled-environment installations common in casinos, airports, and school campuses.
• Compact 4-Channel Form Factor: 6.1 × 5.3 × 1.1 inches (15.5 × 13.5 × 2.8 cm) and under 2 lbs, designed for mounting in small outdoor enclosures, pole boxes, or equipment racks without bulk penalties. LED status indicators confirm link and activity per channel.
• MTBF >100,000 Hours: Solid-state current limiters and circuit board built to IPC standards. Expected life of roughly 11 years at continuous operation before statistical failure mode—relevant for unmanned outdoor camera deployments where field service is costly.
• User-Selectable Data Rate: DIP-switch configuration lets you dial in 10 or 100 Mbps per channel, optimizing for distance or throughput depending on cable run length and camera resolution.

Integration & Compatibility

The CLLFE4POEU works with any standard ONVIF IP camera or 10/100 Mbps Ethernet device—no proprietary firmware or VMS integration required. It transparently extends the Ethernet and power layer, so your existing IP cameras and access control systems function as if they were plugged directly into your network switch. It integrates with PoE+ managed switches for upstream control and integrates with network video recorders via standard Ethernet bridging. For power-starved remote nodes (electric strike locks, strobe beacons, or multi-sensor housings), the injection mode with external 48–56V supply is the standard retrofit solution in large-scale surveillance projects.

What's in the Box

The four-channel CLLFE4POEU kit includes 1x Local module and 1x Remote module. Both are required for operation; they are field-paired units and cannot be separated. No patch cables, power supplies, or brackets are included—you source those separately based on your site conditions and mounting platform.

Frequently Asked Questions

Q: Does the CLLFE4POEU support 802.3af PoE (low-power devices)?

A: Yes. It complies with IEEE 802.3af/at, so it passes through or injects power for both low-draw devices (13W or less) and high-draw PoE+ gear (up to 30W). Check your camera or device datasheet to confirm power draw; if it's under 30W, the CLLFE4POEU can supply it.

Q: Can I run the CLLFE4POEU at 100 Mbps over the full 3,000-foot distance?

A: No. At 100 Mbps full bandwidth, the UTP distance limit drops to 2,000 feet. If your camera streams at high frame rate or high resolution (4MP+), the 2,000-foot range at 100 Mbps is the practical limit. For longer runs, switch to 10 Mbps mode or use coax (which extends to 5,000 feet at 10 Mbps).

Q: What power supply do I need for Local mode injection?

A: A regulated 48–56V DC supply rated for at least 30W (roughly 0.6A at 50V). This is sold separately and must be sourced from a power supply vendor or bundled by your integrator. Do not connect 24V AC or unregulated supplies—it will damage the unit.

Q: Is the CLLFE4POEU NDAA Section 889 compliant?

A: Evidence provided does not include NDAA or Section 889 certification claims. If you require NDAA compliance, contact the manufacturer or your integrator to confirm eligibility or request certification documentation.

Q: Can I daisy-chain multiple CLLFE4POEU units to reach even longer distances?

A: Not recommended. Each unit is a point-to-point extender (Local to Remote pair). Chaining introduces latency and packet loss. For multi-segment long-distance runs, use separate Local/Remote pairs with intermediate equipment, or consult Comnet technical support for custom topology guidance.

Q: What is the warranty on the CLLFE4POEU?

A: Comnet offers a lifetime warranty on the CLLFE4POEU. Check the manufacturer website or contact support for terms and conditions.

The Comnet CLLFE4POEU solves a specific installation problem: you have a network switch or PoE+ injector in a central location (server room, electrical closet), but your IP cameras, access readers, or network devices are scattered across a 2,000- to 3,000-foot footprint—parking lot edges, rooftop corners, distant warehouse wings. Rather than pull new fiber or licensed conduit, the CLLFE4POEU lets you reuse existing CAT-5 UTP or coax and inject full 30W PoE+ power over those runs. It's a point-to-point copper extender, not a switch, so you're buying simplicity and distance reach.

Technical Highlights:

• 3,000-foot UTP reach at 10 Mbps; 2,000 feet at 100 Mbps: Meaningful spec because most IP cameras top out at 5–8 Mbps sustained bitstream for H.265 on moderate resolution (4–5MP). At 10 Mbps mode and 3,000 feet over UTP, you're not throttling a typical camera. Full 100 Mbps mode reserves distance for higher frame rate or multiple devices per channel.
• 30W PoE+ injection (48–56V input): Handles the power budget for a 4MP turret camera (8–12W) plus a pan-tilt-zoom base (15–20W) or a multi-sensor outdoor enclosure. One external 30W supply powers the entire Local module; no individual per-device power packs at the Remote end.
• Four independent 10/100 Mbps channels: Each channel is isolated electrically and bandwidth-wise. A full-frame-rate 4K camera on channel 1 does not steal bandwidth from a 2MP access reader on channel 4. Critical when you're mixing high-bitrate video with low-bitrate access control on a single copper run.
• NEMA TS-1/TS-2 certification with -40°C to +75°C operating range: Third-party lab tested for transient voltage protection, humidity swings, and mechanical shock. If your Remote module is mounted in an unheated pole box or outdoor cabinet with thermal cycling, this rating confirms the unit won't degrade in year 2 or 3.

Deployment Considerations:

• Distance-to-bandwidth tradeoff is real: If you need 100 Mbps symmetrical throughput for high-bitrate 4K or dual-sensor cameras, you're locked to 2,000 feet UTP max. At 3,000 feet, drop to 10 Mbps mode—fine for standard 2–4MP single cameras but not for video analytics requiring full frame rate or fast shutter speeds.
• Power supply sourcing is your responsibility: The CLLFE4POEU does not include a 48–56V injector. You must source a regulated supply (not panel supply, not 24V)—a common gotcha in retrofit jobs where integrators forget to spec or budget the injector separately.
• Coax extension is slower but longer: If you have existing coaxial runs (old analog CCTV plant), the CLLFE4POEU can reuse them and extend 5,000 feet at 10 Mbps. This is the retrofit-analog-to-IP path, but you sacrifice speed for distance.

Deploy the CLLFE4POEU when you're retrofitting large campus surveillance (airports, casinos, school districts) where central PoE+ switches or injectors are in one or two server rooms and Remote cameras are scattered hundreds or thousands of feet away. It's not a replacement for fiber backbone or managed switches—it's a point-to-point extender that trades manageability for installation simplicity and distance reach on existing copper.
