For this purpose, the method one) can be adopted by a microprocessor with two AD converter modules; or, the second mode) selects a microprocessor with an AD converter module and is externally connected with an independent AD converter module. One of the AD converter modules is used for AD conversion of a normal analog quantity, and the other AD converter module is used for AD conversion of burst receiving optical power. However, in either method, two AD converters are required, which increases the hardware cost of the OLT optical module, and increases the complexity of the OLT hardware circuit. On the other hand, the method three) may also be adopted to close Trigger interrupt when the conventional analog quantity is sampled, and then open Trigger interrupt after the conventional analog quantity is sampled, but this may result in failure to respond to Trigger interrupt in time, so that a time difference exists between the time of receiving the Trigger interrupt signal and the sampling time of the burst received optical power, and thus the reporting of the burst received optical power is delayed.
