According to the protocol, the OLT regards itself having failed to receive optical signals after it fails to detect any optical signals for consecutive four frames, and then the OLT sets the status of the PON port to down. The upstream optical frequency of the ONU is 8000 frame/s, and 0.5 ms for four frames, so the MA5600T/MA5603T reports the LOS alarm 0.5 ms after its PON port does not receive any optical signals.

As described in the protocol, LOS Loss of Signal The OLT did not receive any expected transmissions in the upstream (complete PON failure) for 4 consecutive frames.
