♕ Ethernet Cable 20m: Cat 8 Ethernet cables are made with a high quality PVC jacket. Tested in over 10,000 bends, it is softer, waterproof, rodent proof and tougher than ordinary PVC material. ♕ Ethernet Cable Shielded: The Cat 8 Ethernet cable uses oxygen free copper wire as the conductor, 4 pairs of twisted pairs with no interference between each pair, and an aluminium foil shield designed to encase the 4 pairs of twisted pairs, which is designed to minimise the effects of internal crosstalk and external electromagnetic interference without loss of throughput.
