Fiber Optic Cable
Fiber
optic cable, also called as optical fiber cable, is a type of Ethernet cable
which consists of one or more optic fibers that are used to transmit data.
Fiber optic cable transmits data as pulses of light go through tiny tubes of
glass. The transmission capacity of optical fiber cable is 26,000 times higher
than that of twisted pair cable.
Twisted Pair Cable
Twisted
pair cable is often used for telephone communications and most modern Ethernet
networks. It is a kind of wiring in which two conductors of a single circuit
are twisted together. A pair of wires forms a circuit that can transmit data.
And the pairs are twisted together to provide protection against crosstalk, the
noise generated by adjacent pairs.
Coaxial Cable
Coaxial
cable, or coax cable, is designed to transmit high-frequency signals. It’s
comprised of a round copper conductor and three layers of insulation and
shielding which prevents crosstalk from motors, lighting and other sources of
EMI. With the shield construction, the coaxial cable can support longer cable
lengths between two devices.
