20ft Cat6 LSZH patch cable

The StarTech N6LPATCH20BK is a 20ft (6.1m) Category 6 network patch cord built with 100% copper conductors and 24 AWG stranded wire. It targets installers and IT teams who need a low-smoke zero-halogen jacket for safer indoor routing. Gold-plated RJ45 contacts and snagless strain relief support reliable termination in dense patch panels.

10GbE performance over 55m

The cable carries 10 Gigabit Ethernet and multi-gigabit speeds up to 55m, rated to 650MHz and compliant with ANSI/TIA-568-2.D. Four-pair U/UTP construction and 24 AWG copper sustain throughput under continuous PoE++ loads without the signal drop-off seen in thinner conductors. ETL verification confirms the sustained performance envelope.

LSZH jacket reduces toxic emissions

The PVC-free PVA sheath limits smoke and halogen release during a fire event, meeting LSZH safety requirements for plenum-adjacent spaces. Snagless boots protect the latch during pulls through conduit, while 50-micron gold pins resist oxidation in long-term deployments. No external power supply or active cooling is involved.

Questions about this item

Does the 24 AWG stranded copper and LSZH jacket stay cool and safe when the cable carries 100 W PoE++ all day?

The 24 AWG stranded copper conductors and PVC-free LSZH jacket are rated for 100 W PoE++ and emit lower toxic fumes under continuous load.

What devices must already have RJ45 ports to use this Cat 6 patch cord?

Both endpoints need RJ45 sockets — such as a router, switch, server, NAS or desktop — to plug the RJ45 connectors at each end.

Will this 20 ft Cat 6 cable run at 10 Gbps alongside my older Cat 5e patch panel and Gigabit switch?

It supports 10 GbE up to 55 m, but the overall link will negotiate to the lowest common speed — 1 Gbps with Cat 5e components.
