摘要

The present invention provides a method and system for the automated collection and storage of calibration data over the entire spectral, power and temperature range of an optical function system. The optical function system includes an optical function device (120) coupled to a controller (102). The automatic calibration system includ es testing instruments, such as a laser source (112), an optical attenuator (113), an optical multimeter (114), and a calibration workstation (115) coupled to the controller (102) of the optical function device (120). The laser source (112) and the optical attenuator (113) apply input signals to the optical function device (120), and the optical multimeter (114) detects the output power of the optical function device (120), The sensed input and output power levels of the optical function device (120) and the output power detected by the optical multimeter (114) are used to generate calibration data that is store d in the controller (102). Since the controller (102) can include a digital microprocessor (107), it can be programmed to store data or to execute particular algorithms as required by a given operational configuration. The controller (102) can be programmed to u se existing photodiodes (103, 104) of the optical function device (120) to measure its internaltemperature during normal operation.
