20-foot Cat8 patch cable for high-speed networking

This 20-foot Cat8 patch cable delivers up to 40 Gigabit data transfer speeds and 2GHz bandwidth using pure bare copper conductors. It is built for IT managers and data centre operators who need a future-proof, high-performance copper link. The double-shielded S/FTP construction suppresses alien crosstalk and electromagnetic interference in dense installations. Snagless RJ45 boots protect the retaining clip during repeated connects and disconnects.

Double-shielded S/FTP design for clean signal

The S/FTP shielding wraps each twisted pair and adds an overall braid to keep the 2GHz channel stable in electrically noisy racks. Pure bare copper wire meets UL Code 444 and TIA568C.2 fire and safety requirements, unlike copper-clad aluminium alternatives. The 28AWG conductors keep the cable flexible for tight patch-panel routing without excessive bend radius. No external power or active electronics are involved, so heat and noise are not factors.

Snagless RJ45 connectors and compliant copper build

Each end uses a standard RJ45 plug with a moulded boot that prevents the latch from catching on adjacent cables or panel edges. The 20-foot length suits cross-rack or floor-to-switch runs while staying within Cat8 channel limits. Pure bare copper construction ensures full standards compliance for permanent-link certification where required. Blue jacket colour aids visual identification in multi-cable bundles.

Questions about this item

How do I install the 145420 cable without damaging the snagless RJ45 boot?

Align the RJ45 plug with the port, press straight in until the retaining clip clicks, and pull gently on the boot — not the cable — when removing it to avoid bending the clip.

What maintenance will the double-shielded S/FTP cable need over time?

Inspect the RJ45 contacts and boot for dust or bent pins every few months; wipe contacts with a dry lint-free cloth and replace the cable if the clip snaps or shielding foil tears.

What limit appears first when running sustained 40 Gigabit transfers on this 20-foot Cat8 cable?

The 2 GHz bandwidth ceiling and 28 AWG conductor gauge set the practical distance limit; at 20 feet the cable meets spec, but longer runs would hit attenuation first.
