Although many people take it for granted, data cabling is one of the most important frameworks for Internet, television and phone usage around the world. Data cabling refers to the structure of cables and networks that is used to transmit digital information from one place to another. Because there are many types of information that are transmitted in this way, there are a variety of types of equipment and supplies.
Unshielded Twisted Pair
One of the most common data cabling devices found throughout the country is the unshielded twisted pair cable, commonly known as a UTP. This can come in many different grades to allow the transmission of all types of data and at different data rates; for example, UTP commonly ranges from telephone-grade up to very high-speed wire. The unique fixture of UTP is that the individual wires within the cable are paired off and twisted together. This helps to eliminate interference from wires within the same cable, thereby allowing for a greater density of wires per foot and, following from that, a heightened opportunity for the transmission of data.
Shielded Twisted Pair
Any data cabling overview would not be complete without a mention of the shielded twisted pair cable, also known as a STP. While more expensive than UTP, the shield mechanism on the wires within an STP cable help prevent the interference of radio and electrical frequencies outside the data transmission source. Therefore, the data cabling use for shielded twisted pair cable is open to many more locations and options than UTP, and it is more secure as well.
Coaxial
One of the most common types of data cabling material found throughout many homes around the world is coaxial. This cable makes use of one single copper conductor. The copper conductor is shielded by a thick plastic layer and a metal shield. As a result of this thick insulation layer and the metal shield, coaxial cables are highly resistant to any form of interference from electrical or radio sources, making them a very secure way of transmitting data.
Fiber Optic
Composed of a central core of glass surrounded by layers of protective shielding materials, fiber optic cable operates by transmitting light instead of electronic signals. This effectively not only limits the problem of electrical interference, but it also allows for rates of data cabling transfer that are much higher than many of the other types of cabling. The fact that this can transmit data much farther than the other types makes it a natural choice for many types of cabling needs at this point.
The individual type of cabling that you'll need for any project at home or at work will depend upon the benefits and disadvantages of the types you're interested in. Consult with a data cabling specialist for more information about how to select the right setup for you.
