Coupling Efficiency

Coupling efficiency refers to how effectively energy, such as light, electrical power, or signals, is transferred from one device or component to another. For example, in a fiber optic system, it measures how much of the light from a source successfully enters the fiber. High coupling efficiency means most of the energy gets transferred with minimal loss, maximizing performance. It depends on factors like alignment, matching the source and receiver, and the quality of connections. Improving coupling efficiency ensures better system performance, less waste, and more reliable operation.
