Advantages of optical fibre cable.
Optical fibre advantages:
- Higher bandwidth : Fiber-optic cable can support dramatically higher bandwidths (and hence data rates) than either twisted-pair or coaxial cable
- Less signal attenuation: Fiber-optic transmission distance is significantly greater than that of other guided media. A signal can run for 50 km without requiring regeneration.
- Immunity to electromagnetic interference: Electromagnetic noise cannot affect fiber-optic cables.
- Resistance to corrosive materials: Glass is more resistant to corrosive materials than copper.
- Light weight: Fiber-optic cables are much lighter than copper cables.
- Greater immunity to tapping: Fiber-optic cables are more immune to tapping than copper cables. Copper cables create antenna effects that can easily be tapped.
- Lesser number of repeater:-
- Electrical isolation: - Optical fibres are fabricated from glass or plastic polymers which are electrical insulators. Hence they do not exhibit earth loop.
- Signal security: - The light from Optical fibre does not radiate significantly & therefore they provide a high degree of signal security.
