Abstract:
1. A method of saving power of an optical network unit comprising: collecting state information of at least one downward physical block and then transiting the downward physical block operating in an idle mode to a sleep mode; transiting an upward physical block to a sleep mode if at least one downward physical block transits to a sleep mode; transiting a data switching block to a sleep mode if the upward physical block transits to a sleep mode; determining a transition of a medium access control block to a sleep mode if the data switching block transits to a sleep mode; transiting an optical transmission-reception block to a sleep mode if the medium access control block transits to a sleep mode according to the determination; transiting the medium access control block to a sleep mode if the optical transmission-reception block transits to a sleep mode; and transiting an operation of a processor to a sleep mode if at least one downward physical block, the upward physical block, the data switching block, the medium access control block and the optical transmission-reception block transit to a sleep mode.
