Optical Modulation Amplitude (OMA)
Optical modulation amplitude (OMA): an indicator in an optical signal test. It indicates the difference between the optical power levels of signal "1" and signal "0" received by an optical module.
Optical Modulation Amplitude (OMA) specifications
ER penalty = 2.23 dB à decrease powers by 2.23 dB. ER penalty = 1.39 dB à decrease powers by 1.39 dB. Short modulator à lower modulator loss.
