Twisted-Pair Cabling: A Guided Communications Media In today’s world, there are many different types of communication media that can be used to accomplish the transfer of some type of data. All of these media are used in almost everyone’s daily life and they all have different aspects that make them a viable option for a user. This paper will delve into one the popular types of guided communications media available, twisted-pair cabling. I will explore how the technology works, its advantages and disadvantages, what is required for the technology and an ultimate “ranking” score for the media in relation others. The first thing we need to understand is what exactly communication medium (or media) is. It is the physical device or substance that transfers the information from one place to another. There are many different types of media which can accomplish this feat but the two main types of media available to use are guided media and wireless media. Guided media are the physical products that carry the data usually over some form of cabling. In this paper we will evaluate a popular guided media: Twisted-pair wiring. (Fitzgerald & Dennis, 2009)

Twisted-pair wiring is a very common type of guided media available in two different types: Unshielded Twisted-Pair ( UTP ) and Shielded Twisted-Pair ( STP ). Unshielded Twisted-Pair is one of the most common and affordable wiring and is used in many Local Area Networks (LANs). Shielded Twisted-Pair has a metal foil surrounding the wires which helps to eliminate crosstalk and alike. UTP cables are widely used in computer networking (today’s Ethernet cables are a form of UTP cabling). (Fitzgerald & Dennis, 2009) The different categories of twisted-pair cabling can offer different speed capabilities; here is a chart with listed speeds for each category and what they are typically used for:

The basis for twisted-pair wiring was actually invented in 1881 by Alexander Graham Bell and has been utilized ever since by thousands of companies, especially and most frequently by telephone companies for voice data transmission purposes. There are many cable companies that manufacture twisted-pair cabling, although some data companies produce their own as well. This technology helped change society because it was one of the basic
