Claim 11:
12. A narrowband interference isolation apparatus, comprising:
at least one processor, configured to determine a parameter of a narrowband interference signal, wherein
the at least one processor is configured to determine 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 a master communication device, and the coefficient of the first filter is for filtering out the narrowband interference signal; and
an interface circuit, configured to send 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.
