Cat. 5e patch cable, 15 m. UV-resistant, durable PVC jacket. 26 AWG wire diameter. Length: 15 m, black. Foiled Unshielded Twisted Pair (F/UTP). In F/UTP cables, all twisted pairs are surrounded by a foil shield, meaning the overall shielding consists of just one layer of foil. Shielded cables exhibit minimal impedance or reactance variations compared to unshielded ones. The transmission parameters remain relatively constant and are better than those of UTP cables, even at high frequencies. Category 5/5e. Cat 5 cables are used for signal transmission at high data transfer rates. They are designed for operating frequencies up to 100 MHz and are suitable for Fast or Gigabit Ethernet. The designation 5e comes from a revision of the standards ISO11801 and EN50173, which made them compatible with Gigabit Ethernet. Cat-5e cables are backward compatible with traditional Cat-5 cables and are more than sufficient for home users in most situations.
