Category 5e (CAT 5e) Network Cabling
Category 5e cable is commonly also referred to as CAT 5e. 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 over each individual pair of copper wires and provides better protection
against EMI.
For best performance of this product, solid core Category 6a/7 STP cable with Category
6a/7 RJ45 connectors is recommended.
USB Cables
USB cables have two distinct 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 5) to the Local
Extender Unit and Remote Extender unit. You may use either the T568A scheme (Table 1) or the T568B
scheme (Table 2) for cable termination as this extender uses all four pairs of the cable. RJ45 connectors are
sometimes also referred to as 8P8C connectors.
