In addition, technical features of various embodiments or individual embodiments provided by the present invention may be arbitrarily combined with each other to form a feasible technical solution, and such combination is not limited by the sequence of steps and/or the structural composition mode, but must be realized by a person skilled in the art, and when the technical solution combination is contradictory or cannot be realized, such a technical solution combination should not be considered to exist and is not within the protection scope of the present invention.

An embodiment of the present invention provides a method for increasing a monitoring power range reported by an optical module, referring to fig. 1, where the method includes: carrying out voltage sampling on the first pin and the second pin; and if the sampling voltage is lower than the preset threshold value, reporting the monitoring power by adopting the sampling voltage of the first pin and the first calibration coefficient.

Based on the content of the foregoing method embodiment, as an optional embodiment, the method for improving the monitoring power range reported by the optical module in the embodiment of the present invention further includes: and if the sampling voltage is smaller than the preset threshold value, reporting the monitoring power by adopting the sampling voltage of the second pin and a second calibration coefficient.

Based on the content of the foregoing method embodiment, as an optional embodiment, in the method for improving the monitoring POWER range reported by the optical module in the embodiment of the present invention, the first pin is an RX POWER pin.

Based on the content of the foregoing method embodiment, as an optional embodiment, in the method for improving the monitoring POWER range reported by the optical module in the embodiment of the present invention, the second pin is an RX POWER1 pin.

Based on the content of the foregoing method embodiment, as an optional embodiment, the method for improving the monitoring power range reported by the optical module in the embodiment of the present invention includes that reporting the monitoring power by using the sampling voltage of the first pin and the first calibration coefficient includes: and correcting the sampling voltage of the first pin by adopting a first calibration coefficient, performing analog-to-digital conversion on the corrected sampling voltage of the first pin, and reporting the received first optical power as monitoring power.

Based on the content of the foregoing method embodiment, as an optional embodiment, the method for increasing the range of monitoring power received and reported by an optical module according to the embodiment of the present invention, where the reporting of the monitoring power by using the sampling voltage of the second pin and the second calibration coefficient includes: and correcting the sampling voltage of the second pin by adopting a second calibration coefficient, performing analog-to-digital conversion on the corrected sampling voltage of the second pin, and reporting the received second optical power as the monitoring power.

Specifically, MCUs P0.1 and P0.2 sample the voltage of RX POWER and RX POWER1 pins, respectively; judging the sampling voltage, and if the sampling voltage is lower than a preset threshold value (the preset threshold value can be any value from 0 volt to 2.4 volts), reporting the external POWER by using the sampling value of RX POWER and a first set of calibration coefficients; when the voltage is larger than the preset threshold value, the external POWER is reported by using the sampling value of RX POWER1 and a second set of calibration coefficient. Referring to fig. 2, after receiving light, the ROSA performs photoelectric conversion, the converted current generates a potential difference through a ground resistor, the MCU performs voltage sampling and determines a sampling voltage interval, and the MCU performs AD conversion on the sampling voltage and reports the received light power. The used MCU reference voltage is 2.4V, and the sampling AD is 14 bits; the ROSA response was 0.7 mA/W.

Firstly, the maximum monitoring optical power can be covered by using a 500 ohm sampling resistor

Using a sampling resistor of 1 kilo ohm, even using the RX POWER point in fig. 3, the maximum sampling current is 2.4V/1k Ω ═ 2.4mA, and the corresponding limit received optical POWER is 2.4mA/0.7mA ═ 3.42W ═ 5.34 dBm; when a sampling resistor of 500 ohms is used, even at RX POWER1 point in fig. 3, the maximum sampling current is 2.4/500 Ω -4.8 mA, and the corresponding limit received optical POWER is 4.8mA/0.7 mA-8.36 dBm; (the max-8dBm requirement can now be met).

Secondly, the monitoring precision under low light can be improved by using a 1 kiloohm sampling resistor;

calculating a calibration coefficient

② reporting the theoretical receiving under different resistances when the light is at-30 dBm

The AD value can jump because the sampling value is easily interfered by the outside under the condition of small sampling value;

the sampling precision can be greatly reduced (exceeding the range of 3 dB) under the condition of small light by using a small resistor; and the segmented sampling can perfectly cover the upper limit of the large light and the precision of the small light, thereby solving the problem that the monitoring range of the module for receiving and reporting is too narrow.

The method for improving the range of the monitoring power received and reported by the optical module provided by the embodiment of the invention can effectively expand the range and the monitoring precision of the monitoring power received and reported by the optical module by respectively sampling and monitoring the two pins.

The implementation basis of the various embodiments of the present invention is realized by programmed processing performed by a device having a processor function. Therefore, in engineering practice, the technical solutions and functions thereof of the embodiments of the present invention can be packaged into various modules.
