What is a keystone jack?

A keystone jack is the socket a network cable terminates into, made in one snap-in size so it fits any keystone faceplate or panel. The cable's eight conductors are punched into the back; the front is the RJ45 socket a cord plugs into. The jack must match the cable's class: Cat 6 cable on Cat 5e jacks performs as Cat 5e, and the wall plate never says so.

Defined by ANSI/TIA-568.2-D, published by TIA.
