Modulation frequency in optical power meters

Home / Modulation frequency in optical power meters

The frequency detected by an optical power meter typically refers to the frequency of a modulated test tone used for fiber identification and continuity testing, not a property of the meter itself. Among them, Optical Modulation Amplitude (OMA) is a central figure of merit for digital (on-off) modulation schemes. This article explains OMA from first principles, shows how to compute it, relates it to other metrics like extinction ratio, and discusses its role in real optical transceivers. Optoelectronic devices which play important roles in high-speed optical fiber networks can offer effective measurement methods for optoelectronic devices including optical modulators and photodetectors.
