OPTICAL NETWORK UNIT AND METHOD FOR CONTROLLING THE UNIT

摘要

Disclosed herein are an optical network unit and a method for controlling the unit. In a passive optical network system, an optical transceiver of the optical network unit performs a wavelength change of an optical signal according to a wavelength setting command transferred from a media access control (MAC) unit and monitors a wavelength change state and reports the monitored wavelength change state to the MAC unit. When the wavelength malfunction occurs, the MAC unit blocks an uplink optical transmission of the optical transceiver.

1. A method for controlling an optical network unit in a passive optical network system, comprising:
performing, by an optical transceiver of the optical network unit, a wavelength change of an optical signal in response to a wavelength setting command transferred from a media access control (MAC) unit; generating, by the optical transceiver, a wavelength threshold alarm in response to a wavelength change and transferring the generated wavelength threshold alarm to the MAC unit; determining, by the MAC unit ,a wavelength malfunction based on the wavelength threshold alarm and a wavelength setting history, the wavelength setting history being history information associated with generating and transmitting the wavelength setting command; and when the wavelength malfunction occurs, the MAC unit blocks an uplink optical transmission of the optical transceiver.
