Optic signal receiver with dynamic control

An optic receiver with system settings responsive to input power comprising:

• a photodetector configured to receive an optic signal and convert the optic signal to an electrical signal;
• an analog front-end system configured to receive, process, and amplify the electrical signal to create an amplified electrical signal, the processing and amplification based on two or more system control values;
• and
• a control unit configured to generate the two or more system control values, such that the processing and amplification is determined by the two or more system control values which are selected from the following:
• equalization values for one or more variable gain amplifier stages, a regulator voltage of a variable gain amplifier, a regulator voltage of a TIA, a regulator voltage of a photodiode, an offset control for a bias loop, and an analog front-end reference current.

An optic module control system, the optic module having a photodetector configured to receive an optic signal and convert the optic signal to an electrical signal, the control system comprising:

• a detector configured generate a detected value representing or related to power of the electrical signal and/or the optical signal;
• a controller configured to:
• process the detected value and develop setting values;
• provide the one or more corresponding setting values to the optic module such that as the detected value increases or decreases beyond or below different threshold values, the setting values also change such that:
• responsive to the detected value of the electrical signal exceeding a first predetermined threshold, adjusting a first optic module setting value;
• responsive to the detected value of the electrical signal decreasing below a second predetermined threshold, adjusting the first optic module setting value;
• responsive to the detected values of the electrical signal exceeding a third predetermined threshold, adjusting a second optic module setting value;
• responsive to the detected value of the electrical signal decreasing below a fourth predetermined threshold, adjusting the second optic module setting value.
