Problems solved by technology

If the power is too high, it will enter the saturation point and generate bit errors. If the power is too low, the receiver will also generate bit errors due to the influence of noise.
Limited by the cost, the hardware circuit can guarantee the reporting accuracy, because the reporting accuracy only needs to meet ±3dB, but it is difficult to guarantee the reporting repeatability, and customers often require the repeatability to meet ±0.5dB

Embodiment Construction

[0014] In order to be able to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0015] The method for reporting the received power of the optical module is that when the received power of the optical module is greater than the first threshold, the current real-time received power is reported to the ONU, and when the received power of the optical module is less than or equal to the fifth threshold, then reported The fifth standard power to the ONU, and when the received power of the optical module is between the fifth threshold and the fourth threshold, the fourth standard power is reported to the ONU, otherwise the current real-time received power and the previous report The difference value of the power is calculated and reported according to the magnitude of the obtained absolute value of the difference value, the fifth threshold value

Abstract

The invention relates to a receiving power reporting method of an optical module. The method comprises the following steps: reporting the current real-time receiving power to an ONU, when the receiving power of the optical module is greater than a first threshold, reporting the fifth standard power to the ONU when the receiving power of the optical module is less than or equal to the fifth threshold, and reporting the fourth standard power to the ONU when the receiving power of the optical module is between the fifth threshold and the fourth threshold; or performing difference operation of thecurrent real-time receiving power and the previous reporting power, and correspondingly reporting according to the absolute value of the obtained difference. By adopting the receiving power reportingmethod of the optical module disclosed by the invention, the real-time reporting is adopted since the received optical power is stable when the optical power is strong; different reporting values areadopted through a setting interval when the optical power receiving is weak, so that the reporting precision is improved, and the reporting efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to the field of communication technology of optical modules, in particular to a method for reporting received power of an optical module and a corresponding microprocessor. Background technique [0002] In order to improve the stability and maintainability of the system, the optical module introduces the digital diagnosis system DDMI. The auxiliary circuit can detect the module's working voltage, laser bias current, laser emission power, module receiving temperature, module temperature, etc. The module can only work normally under the appropriate received optical power. If the power is too high, it will enter the saturation point to generate bit errors. If the power is too low, the receiver will also generate bit errors when affected by noise. Limited by cost, the hardware circuit can guarantee the accuracy of the report, because the accuracy of the report only needs to ...
