Optical Channel

An optical channel is a pathway that carries information using light, typically through fiber optic cables. These channels transmit data as pulses of light, allowing for high-speed, long-distance communication with minimal loss. Think of it as a “superhighway” for digital information, where light signals travel through thin strands of glass or plastic, enabling fast internet, television, and phone services. The optical channel's efficiency and capacity depend on the quality of the fiber and the equipment used to generate and detect the light signals.
