Category 7 cables are backward compatible with Category 5e and Category 6/6A cables. This cable provides performance of up to 600 MHz and is suitable for 10BASE-T, 100BASE-T, 1000BASE-T, and 10GBASE-T. Category 7 cable contains four twisted copper wire pairs like earlier standards, however Category 7 requires that the individual twisted pairs are shielded as well as the whole cable.
Category 7 is not recognized by the TIA/EIA.
Network cabling standards are used internationally and are published by ISO/IEC, CENELEC and the Telecommunications Industry Association (TIA). Since 1995, solid-conductor UTP cables for backbone cabling is required to be no thicker than 22 AWG and no thinner than 24 AWG, or 26 AWG for shorter-distance cabling.
