Appendix: Technical Glossary
Appendix. Technical Glossary
Category 5 (CAT5) Network Cabling — Category 5 cable is commonly also
referred to as CAT5. 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. Category 5 has been superseded by CAT5e cabling, which includes improved
data integrity to support high-speed communications.
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.
Figure 6-1. USB connectors.
RJ-45 — The Registered Jack (RJ) physical interface is what connects the network
cabling (CAT5) to the LEX unit and REX unit. You may use either the T568A
scheme (Table 6-1) or the T568B scheme (Table 6-2) for cable termination. The
1-Port CAT5 USB 2.0 Extender uses all four pairs of the cable. RJ-45 connectors
are sometimes also referred to as 8P8C connectors.
