Title:
OPTICAL COMMUNICATION DEVICE AND POWER-SAVING CONTROL METHOD FOR OPTICAL COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/146665
Kind Code:
A1
Abstract:
A packet monitoring unit (101f) monitors packets transmitted from an ONT device (200ai) and includes a signal-off detection unit (101f1). A power-saving mode flag generation unit (101e) activates a power-saving mode flag (non-power-saving mode, power supply input) when a reset signal is inputted from a MAC unit (102). The power-saving mode flag generation unit (101e) also sets the power-saving mode flag to a sleep state (power-saving mode, power supply cutoff) by using a signal-off detection signal obtained by the signal-off detection unit (101f1) in the packet monitoring unit (101f). The power-saving mode flag generation unit (101e) sets the power-saving mode flag to the active state or the sleep state depending on the packet state in a packet data communication region, but sets the power-saving mode flag always to the active state in a ranging region. A pattern discriminating unit (101g) discriminates between the packet data communication region and the ranging region.
