Some firms have the preference or the requirement that certain parts of their facility or their entire facility be hardwired with network cabling in Chambersburg PA for their network connections. This maximizes the performance of the network cabling by controlling the way each branch is “terminated” and ensuring that the cabling is installed in such a way as to minimize interference. On the other hand, in an office or laboratory setting, the building planners often desire that there be available sockets for attaching network cabling, much as they will provide AC sockets for plugging in computers and other equipment. Providing network sockets is a bit more complicated than providing standard AC wall sockets, and the building planner should consider two things: making sure the socket installation work is contracted with a professional and that they educate employees on the basics of connecting to a network socket.

Most people understand the idea of a resistor, a component which resists the flow of current. Each appliance you plug into the wall has a resistance to the AC power current. Washing machines have a comparatively low resistance, allowing a large current (and associated power) to flow. A radio on the other hand, uses much less current, and has a higher resistance. This is important for network cabling, because the higher frequencies of a network signal give the network cabling in Chambersburg PA a “characteristic impedance”. When the cable is connected to a computer, the computer socket provides a matching impedance to that of the cable. If it does not, then the signal hits the computer and a portion bounces back. The return signal can form large standing waves with the original signal, degrading the network performance. The professional who installs the network sockets understands this, and will route and terminate the infrastructure cables accordingly.

For the employees, some of the rules of thumb are to make the connection from the network socket to the computer or other device as short as possible. This reduces the possibility of interference. The network cable is susceptible to interference from all sorts of sources including nearby high power machinery, nearby power converters, and the signal from the power cord of the computer itself. The interference from these sources can couple to the network cable in a proportion related to its length; for this reason, the shorter the connection, the better.

Although Tee junctions exist for network cabling, they should not be used. Each networked device should be connected to its own socket, in order to preserve the match that the device presents to the cable.
