What is an Optical Fibre System?

Fibre optic cable and equipment is now replacing copper cable and equipment as a means of communication and signal transmission, spanning long distances between local telephone exchanges and providing a backbone for many network systems. In its simplest form a fibre optic system will consist of a transmitter (produces and encodes the light signals), optical fibre (conducts the light signals over a distance), optical repeater (may be required to re boost the signal over longer distances), and a receiver (receives and decodes the light signals).

How does it work?

Fibre-optics use light pulses to transmit information down fibre cable cores instead of using electronic pulses to transmit information down copper wires.

At one end of the optical system is a transmitter. This is the place of origin for information coming into the optical fibre network. The transmitter accepts coded electronic pulse information as signals and then processes and translates that information into equivalently coded light pulses. A light-emitting diode (LED) or an injection-laser diode (ILD) can be used for generating the light pulses. Using a lens, the light pulses are funnelled into the fibre-optic cable where they transmit themselves down the line.

Light pulses move easily down the optical fibre core due to a principle known as total internal reflection. This principle of total internal reflection states that when the angle of incidence exceeds a critical value, light cannot get out of the glass; instead, the light bounces back in. When this principle is applied to the construction of the fibre-optic strand, it is possible to transmit information down fibre cores in the form of light pulses.

At the other end of the optical system the signal that has been transmitted the length of the fibre optic cable run reaches the receiver which then translates the information back to electronic pulses.At the other end of the optical system the signal that has been transmitted the length of the fibre optic cable run reaches the receiver which then translates the information back to electronic pulses.

Fibre Optic Cable Advantages:

• Speed:Fibre cable networks operate at high speeds - up into the gigabits.
• Bandwidth: Fibre cable systems have a large information carrying capacity.
• Distance: Signals can be transmitted via fibre cable further without needing to be "refreshed" or strengthened.
• Resistance: Fibre cable systems provide greater resistance to electromagnetic interferences such as radios, motors or other nearby cables.
• Maintenance: Fibre optic cable costs much less to maintain.
• Higher carrying capacity: Because optical fibres are thinner than copper wires, more fibres can be bundled into a given-diameter fibre cable than copper cable.
• Non-flammable: Because no electricity is passed through fibre cable there is no fire hazard
