There are three types of wired transmission media
  1.   Coaxial cable
  2.   Twisted pair cable
  3.    Fiber optic cable

1.Coaxial cable

A coaxial cable or coax is a cable, used in the transmission of audio, video, and communication. Mainly coaxial cables are used as network and broadband cable. These cables are high bandwidths and greater transmission capacity. These cables have a metal male connector end that is screwed into a female connector.
There are two types of coaxial cable
  • ·         Thinnet (10Base5)
  • ·         Thicknet (10base2)

Thinnet – it is also knowns as thin ethernet or 10Base2. It has 10 Mbps speed, Baseband signal, and 200 meters in length.

Thicknet – is also known as thick ethernet or 10Base5. It has 10 Mbps speed, Baseband signal, and 500 meters in length.

Twisted Pair Cables

Twisted pair cable is very important to network media. It can be used for phone communication and cable Ethernet network. Twisted pair cabling is a type of wiring in which two conductors of the single circuit are twisted together for the purpose of canceling out the electromagnetic interference (EMI) from external sources. There are two kinds of twisted pair cable
  • UTP
  • STP

UTP (Unshielded Twisted Pair)

   UTP means Unshielded Twisted Pair,  a pair of copper wires wound by plastic insulators. UTP is the cheapest form of cable available for networking purposes. It is mostly used in Local Area Network (LAN) Environments. The different types of UTP are CAT5, CAT5e, CAT6, CAT6a and 7.

STP (Shielded Twisted Pair)

   STP stands for Shielded Twisted Pair is a pair of wires wound around each other and placed inside a protective foil wraps as protection from crosstalk and electromagnetic interference (EMI). but it can extraordinarily enhance the signaling rate in the given transmission plot. Twisting gives cancellation of the magnetically induced field and current on a pair of conductors.

Fiber Optics Cables

Fiber optic cable is a fast information transmission medium. Fiber optic cables carry communication signal using pulses of light generated by a small laser or light emitting diodes (LEDs).
                                     It contains minor glass or plastic fibers, which carry light beams and the coating helps preserve the fibers from heat, cold, electromagnetic delay from distinct types of wiring, as readily as some protection from ultraviolet rays from the sun. Fiber optics manages for an essentially faster data transmission than standard copper wires. And the fiber optics cable bandwidth is much higher than other cables.
