OPTICAL FIBRE TRANSMISSION
1.0
INTRODUCTION
Optical fibres also called optical waveguides are thin strands of glass that serves as information transmitters in the form of light pulses. Transmission occurs within the fibre by means of total internal reflection. Due to the speed of light, information is transmitted over long distances in a very short period. Optical fibres can transmit various kinds and volumes of information using different light pulse colour.
Optical fibres can be used conveniently without the need for incessant repeaters as they have minimal attenuation due to the speed of light, which permits them to travel for long distances in the core of the fibre without touching the cladding of the fibre strand.
Optical fibres due to their complex and delicate nature do not allow for information tapping and siphoning as they need to be cut to do so, presenting
