White flat CAT8 Ethernet cable forty feet long with snagless RJ45 connectors

STARTECH

STARTECH NLWH-40F-CAT8-PATCH 40ft White CAT8 Ethernet Cable

SKU CH-695B-8A53V

A 40-foot white CAT8 patch cable with snagless RJ45 connectors, S/FTP shielding and 26 AWG bare copper conductors rated for 25 Gbps, 40 Gbps, 2000 MHz bandwidth and 100 W PoE++

  • Supports 25 Gbps and 40 Gbps speeds with 2000 MHz bandwidth
  • Delivers up to 100 W PoE++ power over the same cable
  • 26 AWG pure bare copper conductors ensure reliable signal integrity
  • S/FTP shielding with aluminum Mylar tape blocks external interference
  • Snagless RJ45 connectors and strain reliefs protect the 40 ft run

40ft White CAT8 Ethernet Cable

This 40ft white CAT8 Ethernet cable delivers 25G or 40G speeds at 2000MHz bandwidth. It uses 26AWG pure bare copper conductors with S/FTP shielding and aluminum Mylar tape. Snagless RJ45 connectors feature strain reliefs for durable patching.

Thermals noise and power draw

The cable supports 100W PoE++ power delivery without active cooling or noise. Shielded construction minimises signal interference during high-throughput transfers. Fluke channel testing verifies reliable performance across the full length.

Upgrade from older category cables

Replaces CAT5e or CAT6 runs when 25G or 40G throughput is required over 40ft. The jump is worth it for 100W PoE++ devices and environments needing 2000MHz bandwidth. Not suited for installations requiring longer unrepeatered distances.

Questions about this item

How do I install the 40ft CAT8 cable and avoid damaging the RJ45 connector?

Route the 40ft length without sharp bends, then push each snagless RJ45 plug straight into the port until the latch clicks; the strain reliefs protect the 26AWG conductors from being pulled out if the cable is tugged.

What maintenance or replacement will this shielded CAT8 patch cord need over time?

Inspect the aluminum Mylar tape shield and LSZH jacket periodically for cuts or crushing; replace the cord if the shielding is compromised or the RJ45 latch no longer holds securely.

What is the first limit I will hit when running 100W PoE++ through this 26AWG cable continuously?

The 26AWG pure bare copper conductors set the thermal limit; sustained 100W PoE++ will heat the cable before the 2000MHz bandwidth or 25G/40G data rates become a bottleneck.
