Claim 0:
1. A narrowband interference isolation method, comprising:
determining a parameter of a narrowband interference signal;
determining, by a master communication device, a coefficient of a first filter based on the parameter of the narrowband interference signal, wherein the first filter is located at a receive end of the master communication device, and the coefficient of the first filter is for filtering out the narrowband interference signal; and
sending, by the master communication device, the parameter of the narrowband interference signal or the coefficient of the first filter to M slave communication devices using an Ethernet operation, administration, and maintenance (OAM) frame, wherein the master communication device is connected to the M slave communication devices, and M is an integer that is greater than 1.
