2.1: Identify types of network cables and connectors

There are three primary connectors you'll see with fiber cables.

A Lucent Connector (LC) Square connector (SC) Straight tip (ST)

True or false? F-type screw-on connectors are used with coaxial cable.

Answer: True. Coaxial cable uses F-type screw-on or BNC twist-on connectors.

True or false? A cable wired with the T568A standard on one end and the T568B standard on the other end works as a crossover cable.

Answer: True. If different standards are used, certain wires are crossed over and the cable will function as a crossover cable. Crossover cables are used to connect similar devices together, such as two computers or two switches.

Twisted-pair cables used in networking have four pairs of wires. The colors of each pair are as follows: ■■ ___ wire and white wire with a blue stripe ■■ _____ wire and white wire with an orange stripe ■■ ___ wire and white wire with a green stripe ■■ ____ wire and white wire with a brown stripe

Blue Orange Green Brown

_____ is commonly used to connect televisions with broadband cable, DVD players, and digital video recorders (DVRs).

Coaxial cable

True or false? RJ-11 connectors are used with twisted-pair cables to connect network devices.

False. RJ-45 connectors are used with twisted-pair cables when connecting network devices.
