Installation
Twisted pair: UTP is thinner and more flexible than other types of cabling,
making it easier to get around the corners, whereas STP is thicker than UTP,
making it more rigid, which can make it more difficult to install around the
corners. STP also requires an electrical ground with the connectors.
Coaxial cable: The connectors for coaxial cable are fairly simple to install, but the
cable is relatively thick and rigid, and can require some finesse in navigating
it around the corners.
Fiber optic: Installation and subsequent testing of fiber-optic cabling is difficult.
Because glass or plastic is used to carry the data, connecting two pieces of
cabling together can provide difficulties, as they must be fused together.
Troubleshooting
Cabling is one of the most common causes of network failure. Most often, the
cable running from the workstation to the wall jack is the one that will be the
problem. This is because the cable runs from central server room or telecom closets
through walls are generally installed by technicians. These cables are hidden
behind walls and ceilings, and are not exposed to the wear and tear of external
cables. To troubleshoot cabling issues,
