20 ft Cat6a Shielded Ethernet Cable

This 20-foot gray Cat6a cable delivers 10 Gigabit network connections with foil-shielded twisted-pair construction. It is built for installers and IT professionals who need reliable, interference-free links over longer runs in offices or conduit systems. The 100% copper conductors support frequencies up to 500 MHz for consistent 10GBase-T performance.

Category 6a practical limits

The Cat6a standard supports 10 Gigabit speeds up to 100 metres, so this 20 ft length sits well within the maximum channel distance. Shielding reduces EMI and RFI noise, which is essential when cables run near power lines or inside dense raceways. Performance depends on every connector and patch panel in the link meeting the same Category 6a specification.

Installation notes

The shielded design adds stiffness compared with unshielded patch cables, so allow extra slack when routing through tight conduits or around corners. Each end must be terminated with shielded keystones or plugs and properly grounded to realise the EMI protection. Mixing shielded and unshielded components can create ground-loop issues that degrade the 10 Gigabit signal.

Questions about this item

Should I choose a different length or colour for my installation?

This cable is supplied in a single 20 ft gray version; other lengths and colours are sold as separate items.

What does the 10 Gigabit rating mean for actual network speed?

The cable is tested to 500 MHz and built for 10GBase-T, so it supports full 10 Gbps throughput over the 20 ft run.

How does the Cat6a shielded design affect the connection?

Foil-shielded twisted pairs block EMI and RFI, preserving signal integrity for reliable 10 Gigabit performance.
