This provides three fully duplex channels. The first channel is used for control purposes and the other two are to carry out either voice or data. The rate at which data travels on these two channels is 64kilobits per second. The two channels can be used in parallel to provide a data transmission of 128Kilobites per second.

So what are fibre optic cables? They are long thin strands of pure glass that are used to transmit signals over long distances. The Core - The thin glass centre where data travels Cladding - Outer optical material that reflects the light back into the core Buffer Coat - Plastic coating protecting the cable. The light in the cable travels through the core by constant bouncing from the cladding (mirror walls) a process called total internal reflection. However some of the light signal degrades mostly because of glass impurities in the fibre. For you to have broadband access with fibre-optics you need - - A Transmitter - receives and directs the optical device to turn light off or on generating a light signal - Optical Fibres - This conducts the light signal over a distance - Optical regenerator - This boosts light signals incase of the signal degrading - Optical Receiver - Takes in the incoming digital light signals, decodes them and sends the electrical signal to the other users' computer. Advantages - Less expensive - Thinner cable - Higher carrying capacity - Less signal degradation - Low power - Non Flammable - Lightweight Above are different ways of receiving broadband internet access and are several ways that society has benefited from internet access. ...read more.
