A method of alarm suppression, comprising: receiving (201), a first optical network device and through a channel optical monitoring, a fault indication sent by a second optical network device is a network device optical adjacent to the first optical network device upflow, where the fault indication includes information indicating one or more defective wave lengths; determining (202), by a control unit of the first optical network device, one or more wavelengths corresponding to a loss alarm LOS signal based on an optical signal configured to be received by an optical transmission constituted the first optical network device, wherein the LOS alarm is sent from the acquisition unit to the transmission control unit; and determining (203), by the control unit of the first optical network device, if one or more defective wave lengths comprise one or more wavelengths corresponding to the LOS alarm; if yes, deleting (204) the LOS alarm.
