This invention relates to the field of communication technology, providing a module and method for burst optical reception detection and indication. The module includes a voltage divider circuit, a comparison and selection circuit, and a D flip-flop. The voltage divider circuit generates a detection signal based on the burst received optical signal. The detection signal is input to the first input of the comparison and selection circuit, and a RESET signal is input to the second input of the comparison and selection circuit. When the RESET signal is low and the detection voltage is higher than a decision threshold level, the detection signal is output; otherwise, a low level is output. The input of the comparison and selection circuit is connected to the clock input of the D flip-flop to trigger the RxSD signal. The RESET signal also flips and is input to the reset input of the D flip-flop, so that when the RESET signal is high, the RESET signal controls the D flip-flop to reset, causing the output RxSD signal to be low. This invention can meet the timing requirements for the normal operation of both protection time and preamble time RESET signals, ensuring normal ONU registration and normal service operation.
