Half-duplex It means data travels in both ways, but in only one direction<br />
at a time.<br />
Full duplex It means data travels simultaneously in both directions.<br />
CABLING<br />
Cabling is a term that can refer to the act of installing the cable and the work<br />
performed before installation begins. Because coaxial cable and twisted-pair cable<br />
are copper cables, and fiber-optic cable uses glass or plastic fibers, different issues<br />
may arise for each type of cable. There are significant differences in how they are<br />
created and installed.<br />
Copper Cabling<br />
Installation of cable requires tools which are used to cut and strip the cable and<br />
to attach the proper connector to the end of the cable. Some of these tools may<br />
include the following:<br />
■<br />
■<br />
■<br />
■<br />
Cable cutter is a tool which is used to cut the cable to the length you<br />
need.<br />
Cable stripper is a tool which is used to strip the cable jacket and expose<br />
the copper wire inside.<br />
Crimp tool is a tool which is used to attach the connectors to the cable.<br />
Connectors are tools that are attached at the ends of the cable.<br />
The pulling force of cabling refers to the amount of force or tension that can be<br />
placed on the cable without damaging it. The minimum bend radius of a cable<br />
refers to how far the cable can be bent before it is damaged.<br />
Fiber Cabling<br />
Fiber cabling also has bend radius and pull force ratings, and during installation,<br />
special tools will be needed to strip the cable so that the appropriate connector<br />
can be attached. These tools include the following:<br />
■<br />
■<br />
■<br />
Cable stripper or ring tool is a tool which is used to remove the plastic<br />
jacket of the cable without damaging the fibers.<br />
Kevlar shears is a tool which is used to cut the kevlar inside the fiber-optic<br />
cable.<br />
Connectors are tools that are attached at the ends of the cable.<br />
Preparing Twisted-Pair Cable<br />
Twisted-pair cabling uses color codes to specify the purpose of each wire and to<br />
make them easily identifiable. Because each wire belongs to a pair, the colors of<br />
each pair are the same, with one solid and the other striped. When connecting
