What does margin mean in optical modules
Optical margin, sometimes called link budget reserve, is the headroom between the power arriving at the receiver and the minimum power the receiver needs to operate correctly. The difference between these power levels is the optical margin. Transmitter power is defined as the minimum peak optical power injected into the fiber by the optical transmitter Receiver. System Margin is a critical parameter in optical communications that determines the reliability and performance of a fiber optic network. In this section, we will explore the definition, significance, and factors affecting System Margin.
