Comnet Copperkit Two Single Channel Ethernet UTP Extenders with Cat5 Cables and Power - CLKFE1EOU

Comnet CLKFE1EOU Ethernet-over-Copper Extender with PoE Pass-Through

The CLKFE1EOU is a single-channel Ethernet extender kit that pushes 10/100Mbps Ethernet data and IEEE 802.3af PoE over standard Cat5 UTP or coaxial cable to distances where conventional switching fails. Deploy this when your powered device (PD) sits beyond the ~330-foot practical limit of a PoE injector — guard booths, rooftop arrays, distant loading dock cameras, or any remote surveillance node on existing building copper.

Overview

This kit includes two single-channel extender units with bundled Cat5 cables and 9-36 VDC/24 VAC power supplies. The transmitter side connects your IP camera or network device and accepts PoE directly from your switch or injector; the receiver side delivers the device to your installation point. DIP switches let you select local/remote mode, 10 or 100Mbps operation, and single-pair or four-pair UTP configuration. Transmission distance depends on cable type and speed: 3,000 feet at 10Mbps over UTP (914m), 2,000 feet at 100Mbps over UTP (610m), or 5,000 feet at 10Mbps over coax (1,524m). Extended temperature operation from -40°C to +65°C handles outdoor and unheated enclosures without derating.

Compatibility

Works with any powered Ethernet device that accepts PoE per IEEE 802.3af — IP cameras, access control readers, sensors, and NVR field nodes. The pass-through PoE design means no separate power supply needed at the transmit side if your switch or injector already supplies power. Supports multicast, unicast, and jumbo frames for video streaming and network protocols. Complies with RFC standards for UDP, TCP/IP, and HTTP/HTTPS traffic; designed to meet NEMA TS-1/TS-2 and Caltrans specifications for traffic and security equipment.

Installation Notes

Mount the compact units (3.3 x 2.5 x 1.1 inches) in cable closets, junction boxes, or weatherproof enclosures. Select cable type (UTP or coax) and speed (10 or 100Mbps) via DIP switches before deployment — no firmware updates required. If PoE power is unavailable at the transmit end, use the included 9-36 VDC or 24 VAC supply. Typical MTBF exceeds 100,000 hours in industrial operating conditions. Symmetric bandwidth delivers virtually zero packet loss across the full usable distance — critical for steady video bitrate over long copper runs.
