Twisted Pair Cable


A twisted pair consists of a pair of insulated conductors that are twisted together. The advantages of a Twisted Pair cable over the two wire open lines are, it provides better resistance from false noise signals. As the two wires are closed to each other, both pick equal interferences caused by irrelevant signal sources and this reduces the differential signal added by the noise.  

Coaxial Cable (coax)


Coaxial cable is a round shape cable in which there is a main conductor wire called inner conductor which is covered with thick plastic insulation of a solid plastic, it foils above it and it is wrapped in metal wire. The outer conductor is called and the top is the plastic pipe which provides protection to all of these.

Coaxial cable is mostly used in cable TV, it is also used in computer networks, but it is currently used very rarely in the computer network. Larger the cable diameter, lower is the transmission loss and higher transfer speeds can be achieved. A coaxial cable can be used over a distance of about 1 KM and can achieve a transfer rate of up to 100 MBPS.    

Optical Fiber Cable


This carries signals in the form of fluctuating light in a glass or plastic cable. An optical fiber cable consists of a glass or plastic core surrounded by a cladding of a similar material. The core transmit the light while the change in refractive index between the core and the cladding causes total internal reflection, thus minimizing the loss of light from fiber.
