Home / What does margin refer to in optical modules

Any optical transmission system requires a defined range of optical receiver input power for proper operation. In practice, the received power must be higher than the minimum level and lower than the maximum level. System Margin (Optical) is a technical concept in RF and microwave engineering related to optical & photonic rf. It refers to a specific parameter, component, or methodology used in the design, analysis, or measurement of radio frequency systems. The clear semi-diameter or semi-diameter of every surface in "automatic" mode, is computed to be the radial aperture required to pass all rays without clipping. For systems with closely spaced elements in or near edge contact, this yields surface apertures that provide no clearance for finishing or.

Semi Diameter Margin

The default value of zero leaves no margin, while a margin of 5% would add 5% to the clear semi-diameter or semi-diameters of all surfaces under "automatic" control.
