Channel
1. A communications path or the signal sent over a channel. Through Multiplexing several channels,
voice channels can be transmitted over an optical channel. 2. A communications path derived from a
specific Transmission medium, as for example Fiber optic cables. The channel supports the end-to-end
communications of an information Source and destination. Besides the transmission medium a
channel needs to have a transmitter/receiver (transceiver) and a modulator/demodulator (modem). By
multiplexing, several channels can share the same specific transmission medium. Channel is
synonymous with link. The term channel is usually employed within the context of multiplexing but not
always.
