Technical Glossary
Category 5e/6/7 (CAT 5e/6/7) Network Cabling
Category 5e/6/7 cable is commonly also referred to as CAT 5e or CAT 6 or CAT 7.This cabling is available
in either solid or stranded twisted pair copper wire variants and as UTP (Unshielded Twisted Pair) or STP
(Shielded Twisted Pair). UTP cables are not surrounded by any shielding making them more susceptible
to Electromagnetic Interference (EMI). STP cables include shielding the copper wires and provide better
protection against EMI.
USB 2.0 Cables
USB 2.0 cables have two distinct full-sized connectors.The Type A connector is used to connect the cable
from a USB device to the Type A port on a computer or hub.The Type B connector is used to attach the USB
cable to a USB device.
RJ45
The Registered Jack (RJ) physical interface is what connects the network cabling (CAT 5e/6/7) to the local
and remote extenders.You may use either the T568A scheme (Table 1) or the T568B scheme (Table 2) for
cable termination as the RG2312 requires all four pairs of the cable. RJ45 connectors are sometimes also
referred to as 8P8C connectors. Note that any give cable must be terminated using the same T568 scheme
on both ends to operate correctly.
