Akingbola and Mrs Yetunde Kolade 3 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

The Fiber Optic Cable: The cable consists of one or more glass fibers‚ which act as waveguides for the optical signal. Fiber optic cable is similar to electrical cable in its construction‚ but provides special protection for the optical fiber within. For systems requiring transmission over distances of many kilometers‚ or where two or more
