Fibre-Optic Telecommunications Systems:

Fibre-optic telecommunications is simply a method of transmitting information from one place to another extremely fast. This is done by shooting pulses of light through an optical fibre. 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. An optic-fibre is a small fibre no thicker than a human hair, either made of glass or plastic that is transparent and flexible. The light inside the fibre-optic cable forms an electromagnetic carrier wave that is

Optical fibre telecommunications has also opened up job opportunities for more technicians to specialize in optic fibre technology.

Mobile Phones

Brief Description of how mobile phones work:

A mobile phone is a device that allows for two people to be connected over the world by a radio link. This is done by connecting to a cellular network, which is provided by telecommunication companies such as Telstra, Optus and Vodaphone being the three main in Australia. Once the cellular network is established it then connects to a cell, which is a tower, then the other phone. If the phone is out of reach from one the original tower the cell may transfer the call to another cell, this process is now so efficient and fast that both caller and receiver would never notice that this has taken place. This uses electromagnetic waves between substation-to-substation this is a combined technology of radio and the telephone. Modern day mobile phones have a wide variety of uses compared to the original mobile phones such as calling, text messages, multi-media messages, email, internet access, games, applications, calculators, music, videos, high resolution cameras and many other options that a only on some devices these are things like Microsoft capabilities and also GPS systems.
