Immunity to electromagnetic interference
Low attenuation loss over long distances
Security of information passed down the cable
optical fibres are used to transmit communication signals
in medicine, optical fibres are used in endoscope and laproscopes.
Uses of optical transmission
1. telecommunication to transmit data in the form of telephone signal.
2. transmit data at very high speed for Internet communication.
2] The advantages of optical fibre over metallic cable is :
(i) Optical fibres have greater bandwidth ,
(ii) Low noise and better reliability ,
(iii) Faster speeds ,
(iv) Optical fibre can carry signals to the longer distances ,
