Impact of Optical Fiber in Voice Signal Transmission

The data transmission owes its existence to the need to transmit data at greater or lesser distances over wire lines that are often sensitive to interference. The raison d'être of any data transmission system is the distribution of error-free information. The criteria for choosing a type of data transmission are the bit rate, the distance to be covered and the cost of the system. Communicating and transmitting information is an essential part of everyday life; because there is communication when we speak, read or write. The five sensory organs (seeing, hearing, smelling, touching and tasting) form the basis of communication in our lives. In general, communication is an exchange of information. There are two: two-way communication (examples: dialogue, telephone conversation), where two subscribers are active, and one-way communication (examples: reading or writing a letter or book, watching television), where there is only one active subscriber.
