Abstract
A self-contained calibration method for improving stability of an optical source in an optical network test instrument includes performing a temperature sweep test of the optical source. Optical output power of the optical source is periodically measured. A temperature correcting value is generated based on the measured optical output power. The optical output power of the optical source is adjusted by applying the temperature correcting value to obtain a substantially constant optical output power of the optical source.
