Which cabling type is designed for communication over long distances?



Which cabling type is specifically designed to transmit communication signals over very long distances?

A) FireWire

B) Twisted pair

C) Fiber optics

D) Coaxial cable


The answer: C) Fiber optics

Because fiber optics uses light to transmit information, a large amount of information can be transferred very quickly over very long distances.


The incorrect answers:

A) FireWire
FireWire, also known as IEEE 1394, is designed to provide connectivity to a local computer.

B) Twisted pair
Twisted pair copper cabling can extend across hundreds of meters, but the electrical signal over copper wires degrades relatively quickly compared to fiber optics.

D) Coaxial cable
Coaxial cable is also copper-based, so its distance is limited compared to fiber optics.

The cable is the important component that links all of our networked devices together, but it’s a critical link that’s often overlooked. In this video, we’ll learn the importance of plenum-rated cable, explore the differences between copper and fiber, and examine network cabling types such as RS-232, USB, and FireWire. We’ll also examine the most common network connector types and discuss some troubleshooting methods you can use to keep your network cabling working perfectly.
