Optical modulation amplitude

From Wikipedia, the free encyclopedia

In telecommunications, Optical Modulation Amplitude (OMA) is the difference between two optical power levels, of a digital signal generated by an optical source, e.g., a laser diode, where P ₁ is the optical power level generated when the light source is "on," and P ₀ is the power level generated when the light source is "off."

OMA = P₁ − P₀

Note: The OMA may be specified in mW or OMA/2 may be given in dBm.
