Optical module and its control circuit and method

Abstract

The present invention relates to an optical module and its control circuit and method. An embodiment provides a control circuit for an optical module, the optical module includes a light receiving unit and a light emitting unit, the control circuit includes: a first memory for storing in a predefined location of the first memory a plurality of configuration parameters of the optical module; a second memory for storing a plurality of variables at a dynamically allocated location of the second memory, the plurality of variables including variables corresponding to the current operating state of the optical module and an analog-to-digital converter configured to receive an analog signal corresponding to the current operating state of the optical module, and convert the analog signal into a digital value, which is stored as a variable corresponding to the current operating state of the optical module in in the dynamically allocated location of the second memory.

Description

technical field [0001] The present invention generally relates to the field of optical communication, and more particularly, relates to an optical module with a digital diagnostic monitoring (DDM) function and a control circuit and method for the optical module. Background technique [0002] An optical module is a core component of a modern optical communication system, and generally includes an optical receiving module, an optical transmitting module, an optical transceiver module, and an optical forwarding module. As a typical example of an optical module, an optical transceiver module, also called an optical transceiver (optical transceiver), generally includes an optical transmitting unit, an optical receiving unit, and a control circuit. With the development of optical communication technology, optical modules generally have a digital diagnostic monitoring function (DDM: Digital Diagnostic Monitoring), so that the system can query and monitor the working status of the o...
