OPTICAL FIBRE ADVANTAGES AND DISADVANTAGES

Fibre optic cabling is immune to electrical interference. Signals are transmitted in the form of ‘off and on’ light pulses similar to a flash light. No electricity is present in transmission over fibre. Thus signals carried on strands of fibre do not interfere with each other. Therefore fibre can be run in areas without regard to interference from electrical equipment.

Advantages of fibre cabling are:

  1. Low transmission loss: This permits longer repeater sections than with coaxial cable systems, thereby reducing costs.
  2. Wide bandwidth: This means a large channel carrying capacity.
  3. Small cable size and weight: This means that drums of cable can be run economically and that each cable uses less space in ...
