Display Epon-Oam Interface - H3C S7500E Series Command Reference Manual

Because location distance and external conditions of each ONU are different, the received signal
maybe strong or weak. AGC time is the time used by the OLT to automatically restore the strength
of the received signal to an acceptable level.
CDR time is the time used by the OLT to synchronize the phase and frequency of received
signals.
ONU laser on time is the interval between when the ONU laser is turned on and when it becomes
stable. ONU laser off time is the interval between when the ONU laser is turned off and when it
becomes stable.
