What Are Wide Area Network And Fiber Optics ?
fiber optics: One of the most reliable and sophisticated telecommunication channel that transmits data up to several billion bits per seconds. This is about 15 times faster than the coaxial cable. Fiber optics uses hair-thin filaments of glass and works on light pulses generated by laser. It can carry voice, data, and video with much more reliability than the other channels. There are better in terms of size and weight as well, half-inch diameter fiber optic can carry up to 60,000 channels in a coaxial cable. Wide Area Network When links are spread over geographical distances like, countries or continents over telecommunication lines, it is referred to as WAN communication facilities like telephone lines, micro waves or satellites are used in this type of network.
