Ultra-slim 4 ft Cat6a patch cable for dense racks

This 4 ft Cat6a cable uses a 28 AWG bare-copper construction and a 4.0 mm jacket to deliver 10 Gigabit Ethernet in high-density patch panels, server racks and data-center cabinets. It is built for installers who need maximum port density and improved airflow without sacrificing 10GBASE-T performance at 500 MHz.

Simple snap-in install; watch bend radius on 28 AWG

The RJ45 plugs feature 50-micron gold-plated contacts and a transparent slim snagless boot that protects the locking clip during routing and re-patching. Because the conductors are thinner 28 AWG, avoid sharp bends or excessive pulling force that could damage the cores or degrade signal integrity over time.

Verify 10GBASE-T gear and rack space before ordering

Confirm that your switches, routers, servers or PoE devices support 10GBASE-T over the full 100 m Cat6a channel, and that your patch-panel ports accept the slimmer 4.0 mm boot. The cable is backward compatible with Cat6 and Cat5e links, but 10 Gb/s speeds require compliant hardware at both ends.

Questions about this item

How can I confirm the cable is delivering a 10 Gigabit link after I plug it in?

Check the switch or NIC LEDs — they should show a 10 Gbps link light, and the connection should remain stable at the rated 500 MHz bandwidth over the full 100 metre Cat6a distance.

What comes with the cable and is anything else required for a typical patch-panel install?

The package contains only the 4 ft slim Cat6a patch cord with RJ45 plugs on both ends; no extra hardware is needed for a standard keystone or patch-panel connection.

When should I choose this 4 ft 28 AWG slim version instead of a standard Cat6a cord?

Pick this 4.0 mm OD cable when rack density is tight — its thin jacket fits more runs per rack unit, bends easily behind panels and improves airflow compared with a typical 6.9 mm cord.
