Twisted Pairs Vs. Braided Cables

Posted by Samantha Flannery on Dec 12, 2018 10:00:00 AM
There are many different types of cables, designs and purposes. In this article, we will be breaking down the comparison between twisted pairs and braided (coax) cables and how they provide connections and how they are different for a network. Data or information, is essentially carried through cables and connectors to provide the proper connection. Each cable has different features and reduce that possibly for interference. 
 
Twisted Pairs:
 
Twisted pair cables (view image below) are used for telecommunications. This cable has twisted pairs of insulated wire. All Category cables that are used in networking applications have twisted pairs. Two types of twisted pair cable that are commonly used:
  • Unshielded twisted Pairs (UTP
    • Less expensive of the two
    • More susceptible to outside interference 
  • Foiled/Unshielded Twisted Pairs (F/UTP)
    • Containts an overall foil shield

Braided Cables: 
 
These are typically known as coaxial cables (view image below). Braided (coaxial) cables have two conductors and contain a center conductor and an outer conductor separated  by an insulated shield. They are generally less expensive and used for a number of different  frequency transmissions. For example, they are widely used for cable TV and video connections and video signals between components such as DVD players, VCRs or receivers. There are also two different types: 
    • 75 Ohm- transmit video signals
      • Type F connector
      • BNC and RCA connectors are often found
    • 50 Ohm- transmission of data signals in a two-way communication system
      • Computer Ethernet, wireless antenna cables, cell phone systems

Comparison:
  • Coax cables are used in almost every home for cable TV connections.
  • Coax cables are popular in local area networks (LAN) because they are highly resistant to signal interference.
  • Twisted pairs are thinner with two conductors twisted together and are better suited for when cost and installations are an issue
