What this cable is and who it suits

This is a Cat8.1 S/FTP patch cable built with 100% bare copper conductors and 24 AWG stranded wire. It carries 40 Gbps at frequencies up to 2 GHz and supports PoE++ up to IEEE 802.3bt. The 3 ft length suits short rack-to-rack or patch-panel links in data centres and high-density wiring closets.

Check before ordering

Verify that both endpoints use RJ45 ports rated for Cat8.1 or Class I performance. Ensure the equipment supports 25GBase-T or 40GBase-T signalling to use the full bandwidth. Confirm the 3 ft reach fits your rack layout without tension on the connectors. The stranded construction is intended for flexible patching, not solid-core horizontal runs.

Thermals noise and power

Passive copper cabling produces no heat and no audible noise during operation. The S/FTP shielding with foil-wrapped pairs and an overall aluminum braid suppresses alien crosstalk when cables run in tight bundles. Gold-plated contacts rated at 50 micro-inches resist corrosion, keeping resistance stable over the cable lifetime. Power delivery follows the connected PoE standard without adding loss.

Questions about this item

Does the 3 ft Cat8.1 cable come with both RJ45 ends already attached, or do I need to buy connectors separately?

Both RJ45 connectors are factory-fitted with 50 micro-inch gold-plated contacts and snag-free boots, so the cable is ready to plug in without extra parts.

The listing mentions 40G and 25G speeds — which one should I expect on my 10 GbE switch?

The cable is certified for 40GBase-T and 25GBase-T, so it will comfortably handle 10 GbE and leave headroom for future upgrades.

What does the 2000 MHz rating actually deliver when the cable is installed in a rack?

At 2000 MHz the S/FTP construction — foil on each pair plus an overall braid — suppresses alien crosstalk, letting 40 Gbps signals stay clean over the full 3 ft run.
