High-Speed CAT8 Cable

This 50 ft CAT8 Ethernet cable supports data transfer speeds up to 40 Gbps with a 2000 MHz bandwidth. It uses 100 % bare copper conductors in a 4-pair shielded twisted-pair construction. Gold-plated RJ45 connectors provide corrosion resistance for reliable long-term connections. The flat profile measures only 0.11 in thick for easy routing along walls and corners.

40 Gbps Throughput Decides Fit

The single specification that determines suitability is the 40 Gbps maximum data rate paired with 2000 MHz bandwidth. This meets 25GBASE-T and 40GBASE-T application requirements. Backward compatibility with earlier RJ45 equipment means it works with existing routers, switches and modems. Buyers needing only 1 Gbps or 10 Gbps links will not utilise the full headroom this cable provides.

Handles 40G Links Up to 50 ft

At 50 ft the cable comfortably carries 40 Gbps signals within the CAT8 channel limits. The shielded S/FTP design suppresses EMI and crosstalk for stable throughput. Operating range spans -20 °C to +75 °C, and the UV-resistant PVC jacket withstands direct sunlight for outdoor runs. Installations requiring longer single-cable distances or higher than 40 Gbps speeds exceed this product's rated capacity.

Questions about this item

Will the 40 Gbps rating hold over the full 50 ft run?

The cable meets Cat 8 specifications for 25GBASE-T and 40GBASE-T, so the 50 ft length is within the standard channel limit and the rated speed is maintained.

Does the 2000 MHz bandwidth require a special RJ45 port?

No, the gold-plated RJ45 connectors follow the standard 8P8C pinout and work with any Cat 5e, Cat 6, Cat 6a or Cat 7 port, though the link will run at the lowest common speed.

How thick is the flat jacket and will it fit under a door?

The flat profile measures 0.11 in thick, thin enough to slide under most interior doors and run along skirting boards without snagging.
