ABSTRACT:
An intelligent fiberoptic receiver (500) and methods of manufacturing and operating the same. During calibration procedures for the receiver, the optical-to-electrical conversion device (avalanche photodiode (501) or PIN photodiode) and its supporting control and monitoring circuits in the receiver module are characterized over a defined operating temperature range. Characteristic data and/or curves defining these operational control and monitoring functions over the range of operating conditions (temperature, power supply) are stored in non-volatile memory (526) such as EEPROM. During operation, an embedded microcontroller (520) together with analog to digital converters (532), digital to analog converters and other associated circuitry, dynamically control the operational parameters of the module based on the current operating conditions (temperature, power supply).
