## Summary description

LANBERG Cat6 networking cable U/UTP, length 305 m, 23 AWG copper conductors and up to 250 MHz frequency. Unshielded twisted pair (U/UTP) design suitable for Ethernet installations, patch panels and structured cabling. Supplied as a bulk reel in black, no pre-terminated connectors — ideal for professional installers and custom crimping.

## Long description

The Lanberg LCU6-21CU-0305-BK is a Category 6 U/UTP networking cable, 305 meters long, designed for structured cabling and high-speed Ethernet connections. It uses 100% pure copper solid conductors (AWG 23, 4 pairs of 2 × 0.55 mm) with HDPE insulation and a 6.0 mm PE outer sheath. The cable is black and features a printed length counter at every meter. It is specified to operate up to 250 MHz and is supplied in a color inner box with a master carton. Packaging dimensions are 35 × 35 × 25 cm.
Advantages
The solid 100% copper conductors provide stable signal transmission and lower resistance over distance compared with copper-clad alternatives. Category 6 U/UTP construction supports data rates and bandwidth suitable for Gigabit Ethernet and applications up to 250 MHz. A meter-printed length counter simplifies installation and measurement, while the black PE jacket offers standard mechanical protection and a neutral appearance for indoor deployments.
Suitable for
Structured cabling for offices, homes, and data closets
Gigabit Ethernet and other high-speed LAN applications
Horizontal and backbone cabling runs up to 100 m

How to use
Uncoil the cable carefully from the reel and follow standard installation practices for Category 6 U/UTP cabling. Maintain appropriate bend radius and avoid excessive pulling force. Terminate with compatible RJ45 connectors and keystone jacks rated for Cat6 using the recommended guide diameter where applicable. For horizontal links keep channel length within 100 m to ensure performance.
Usage recommendations
For best performance, perform certification testing after installation (wiremap, attenuation, near-end crosstalk, and return loss). Avoid running the cable parallel to power lines or near strong electromagnetic sources. Store and transport the roll in its original packaging to protect the jacket and printed meter markings.
