Techopedia Explains Category 7 Cable

The Cat 7 cable is similar to the Cat 6 cable. Each has the same four-pair of twisted cables that support 10 Gbps Ethernet networks and stretch to 100 meters in length. It can provide a bandwidth speed of 600 MHz.

The Cat 7 cable provides more enhanced performance against crosstalk and attenuation than its previous peers by requiring that each pair be completely shielded and form a screen-shielded twisted pair (SSTP) or screen-foiled twisted pair (SFTP) based cabling. It is used in Gb Ethernet and 10 Gb Ethernet networks.

Moreover, the Cat 7 cable’s overall lifespan is 15 years.
