Comparative Analysis of Fiber Optic Voice Link Using Intensity Modulation in Commercially Available Optical Fibers
Communication is the method by which two persons can share any meaningful information with each other at an instant. It requires a sender who wants to communicate, message which is to be conveyed & receiver who receives this message at the receiver end. Now a days due to the advancements and technology, digital communication is receiving wide attention among researchers. Digital communication is achieved by sending digital messages in form of pulses 0 & 1 through modem. Modem is mediator to transfer the message which consists of both modulator & demodulator. The communication can only be possible with modulation.
