5. 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 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 provide 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 Category 5 has been superseded by CAT5e cabling, which includes improved data integrity to support high-speed communications.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 5-1. USB Type A and Type B cable connectors.

RJ-45: The Registered Jack (RJ) physical interface is what connects the network cabling (CAT5) to the local unit and the remote unit. You may use either the T568A scheme (see Table 5-1 and Figure 5-2) or the T568B scheme (see Table 5-2 and Figure 5-3) for cable termination. RJ-45 connectors are sometimes also referred to as 8P8C connectors.
