Black Cat8 ethernet cable twenty feet long with snagless RJ45 connectors

Monoprice Inc.

Monoprice 145448 Cat8 network ethernet cable 20 feet black S/FTP 28AWG 2GHz 40G

SKU CH-MWK8-KCXK1

A 20‑foot Cat8 patch cable with double S/FTP shielding, 28 AWG pure copper conductors, 2 GHz bandwidth and 40 Gbps transfer speed

  • TypeNetworking Patch Cables
  • FeaturesDouble Shielded (S/FTP)
  • Up to 40 Gbps transfer speed supported by 2 GHz bandwidth
  • Double S/FTP shielding reduces interference for reliable data transmission
  • Snagless RJ45 boot protects the plug retaining clip during handling
  • Pure bare copper conductors meet UL 444 and TIA 568C.2 fire safety standards
  • 20 foot length with 28 AWG gauge suits typical patch cable runs

Monoprice Cat8 20‑foot S/FTP cable

This 20‑foot Monoprice Cat8 patch cable uses double‑shielded S/FTP construction with 28AWG pure bare copper conductors. It is built for installers and network engineers who need a verified 40 Gbps link over copper without moving to fibre. The snagless RJ45 boot protects the retaining clip during repeated patch‑panel changes.

Double‑shielded design for dense racks

The S/FTP shielding rejects alien crosstalk in crowded cable trays, letting the cable sit alongside power runs or other data bundles without extra conduit. Its 28AWG gauge keeps the cable flexible for tight patch‑panel routing, while the snagless boot prevents clip damage when pulling through cable managers. Pure bare copper meets UL 444 and TIA‑568C.2 fire‑safety requirements for plenum‑adjacent installs.

2 GHz bandwidth and 40 Gbps headroom

Rated to 2 GHz bandwidth, the cable supports 40 Gbps Ethernet up to the full 20‑foot length, covering most top‑of‑rack and server‑to‑switch links. Runs longer than 30 feet or installations needing 100 Gbps will exceed the copper specification and require fibre instead.

Highlights

Questions about this item

Does the 28 AWG gauge limit the 40 Gbps speed over the full 20-foot run?

The cable is rated for up to 40 Gbps and 2 GHz bandwidth at its 20-foot length using 28 AWG pure bare copper conductors.

Will the double S/FTP shielding and 28 AWG construction keep heat and noise low during all-day 40 Gbps traffic?

Passive copper cables generate no audible noise; the S/FTP shielding and 28 AWG pure copper conductors minimise signal loss and heat even under continuous 40 Gbps loads.

What equipment must already have RJ45 ports to use this Cat8 cable at its rated 40 Gbps?

Both ends need devices with standard RJ45 Ethernet ports — such as switches, routers, servers or NICs — that support 40 Gbps operation.
