An optical module that dynamically adjusts the range of optical power reception

The application relates to the field of optical communication, in particular to the technology of optical power receiving range of dynamically adjusting optical modules in passive optical networks. In an optical module that dynamically adjusts the range of optical power reception, the optical signal receiver receives the optical signal; the avalanche diode converts the optical signal to the photocurrent; the optical power detection module obtains the optical power value of the photocurrent; the main control chip adjusts the resistance of the variable feed resistance circuit according to the optical power value; The guided amplifier is based on the resistance of the variable feedback resistor circuit and the output voltage of the photocurrent. Through the scheme provided by this application, the resistance value of the variable feedback resistance circuit is adjusted according to the optical power value, and then the feedback gain is adjusted. The output range of the transconductance amplifier output voltage Uout is controlled within the appropriate range. The error rate is effectively reduced and the range of the receiving light power range of the extended optical mode block is enhanced. The robustness of the system.
