Network cabling tutorial for professional low voltage installers - How to set up network cabling in a business


The option of network cabling (or communication medium as it is often called) is rather essential because of the extremely high frequencies of the signals. Sending out a 60-cycle energy power through a wire seldom presents a problem; however sending a 100 million bits per second signal can be a little bit more challenging. For this reason, the approach of sending signals and the products they are sent through can be important.


Network Cabling Types

A variety of cabling alternatives are available for networking connections.

Unshielded Twisted pair (UTP) - UTP cable television is the main cable utilized for networks, as specified in the EIA/TIA 568 requirement. This cable type has been extensively used since it is inexpensive and simple to install. Minimal bandwidth (which equates into slower transmissions) has pressed advancement of new cable television grades (the "cagegories" of 568) but has developed a more expensive product and more complicated installation process.

Screened Twisted pair (ScTP) - Same as UTP with a total guard around the 4 pairs. While not presently specified for any networks, it is allowed in the EIA/TIA 568 requirement, it is utilized in lots of networks in Europe where EMI is a higher issue. It tends to be more pricey, harder to end and requires special plugs and jacks.

Protected Twisted Pair (STP) - Like UTP however with a guard around every set. Commonly used in IBM systems (IBM Type 1 cable television) and consisted of in 568. Now mainly used in Europe and for some very high speed networks.

Coaxial Cables - Original Ethernet, used in CATV systems. This is familiar and easy to install, has great bandwidth and lower attenuation however more pricey, large. Not included in 568, however in 570 for residential use.

Optical Fiber - Optional for many networks, leading performance, exceptional bandwidth, long life expectancy, outstanding security but slightlly higher installed cost than twisted set cable televisions, more expensive electronics user interface to them. Fiber can be cost efffective with optimum architecture. See Lennie Lightwave's Guide To Fiber Optics.

Other transmission choices:
Wireless - WiFi or cellular - No information transmission cable televisions are required to connect any specific terminal, but wireless requires cabling to every antenna (called a Gain access to Point), so it's hardly "wireless"!. Within the variety of the radio signals, a linked device can be moved anywhere. In the modern-day network, wireless is a requirement due to the fact that a lot of users want "mobility" - so they are not "tethered" to a desktop.

Infrared Transmission - Also sends without wires to the terminal by utilizing infrered (IR) light but each transmitter needs cabling. By sending out pulses of infrared light in the very same patterns as electronic pulses sent out over cable televisions, it is possible to send information from one location to another. Networks based upon IR transmission have actually been established for use in office and for line-of-sight transmissions in between structures.
