1. An authentication method, comprising:
in a case where an optical line terminal (OLT) operates in at least two bands, setting at least one low-delay band and at least one non-low-delay band;
after receiving, in a non-low-delay band of the at least one non-low-delay band, a first serial number sent by one of an optical network unit (ONU) or an auxiliary authentication device, acquiring an equalization delay;
after receiving, in the non-low-delay band, an authentication request sent by the ONU or the auxiliary authentication device, determining an ONU identifier according to the first serial number or a second serial number of the ONU in a low-delay band of the at least one low-delay band, wherein the second serial number is sent by the ONU in the non-low-delay band; and
authenticating the ONU according to the ONU identifier and the equalization delay.
