Advantage of fibre optics

1. Capacity
Optical fibres carry signals with much less energy loss than copper cable and with a much higher bandwidth . THis means that fibres can carry more channels of information over longer distances and with fewer repeaters required .

2. Size and weight .

Optical fibre cables are much lighter and thinner than coppper cables with the same bandwidth . This means that much less space is required in underground cabling ducts  . Also they are easier to installation engineers to handle .

Fiber optic cable function as a light guide , guiding the light introduced at one ened of the cable through to the other end . THe light source can either be a light emitting diode (LED ) or a lase .

Advantages

3. Securiy

Optic fibres are much more difficult to tap information from undetected , a great advantage for banks and securiy installations .

4. Electrcal interference and insulation

THey are immune to Electromagnetic interference from radio signals , car ignition system , lighting etc  . THey can be routed safetly through explosive or flammab le atmospheres , for example , in the petrochemical industries or munitions sites ,w ithout any risk of ignition .

5. Realibility and Maintenance
Optical fibers is a constant medium and is not subject to fading  , Has a long life span ( 30 years ) . Immune to adverse ( can stand ) temperature and moisture  . Can be underwater cable . Less maintenance because of fever electronic repeaters .

6. Versatility .
Fiber optics communications systems are available for most data , voice and video commmunications formats .

7. Running Costs
Although copper coaxial cable can handle the bandwidth requirements over the short distances of a housing scheme , a copper system consumes far more electrical power than fibre  , simpley to carry the signals . THerefore optcal fibres are cheaper in the long run .

8. Expansion
Easily expanded if properly designed  .
