Type 1 - Two 22 AWG solid core pair of STP cable with a braided shield.
This is the normal cable between MAUs and computers.
A braided shield surrounds two twisted-pairs of solid copper wire. Type 1 is used to connect terminals and distribution panels or to connect between different wiring closets that are located in the same building. Type 1 uses two STPs of solid-core 22 AWG wire for long, high data-grade transmissions within the building's walls. The maximum cabling distance is 101 meters (331 feet).
