Optic fibre

Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber.

The light forms an electromagnetic carrier wave that is modulated to carry information.

First developed in the 1970s, fiber-optic communication systemshave revolutionized the telecommunications industry and have played a major role in the advent of the Information Age. Because of its advantages over electrical transmission, optical fibers have largely replaced copper wire communications in core networks in the developed world.

Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals.

The process of communicating using fiber-optics involves the following basic steps: Creating the optical signal involving the use of a transmitter, relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak, receiving the optical signal, and converting it into an electrical signal.

Satellite Communication

VSAT is a way of providing better connectivity to the internet or for private satellite communications networks in areas where there are unreliable communication networks. Depending on bandwidth requirement (data speed and/or communications channels) VSAT systems can be relatively small (1 to 2.4 meter antenna) and easily installed. By linking VSAT terminals to larger hub stations (or land earth stations) a wireless network can be established at relatively low cost.
