Cat7 cables have four individually shielded pairs within a common umbrella. Due to the close contact arrangement with a RJ45 plug this the standard (IEEE 802.3an) is unable to meet !!! Ergo is a sham.
There are currently two types of connectors for cable Cat7 that meet this standard:
Siemon TERA and Nexans GG45
Because currently all modern RJ45 are based, none is probably to benefit from the time, to use a cable Cat7 technically knowledgeable !!!
