STATION TERMINAL, SUBSCRIBER'S TERMINAL, AND OPTICAL ACCESS NETWORK INCLUDING STATION TERMINAL AND SUBSCRIBER'S TERMINAL

摘要

PROBLEM TO BE SOLVED: To improve use efficiency of a frequency band and reduce power consumption in an optical access network using OFDM.;SOLUTION: OLT changes intensity of local oscillation light source light to be set at ONU according to a change in traffic or required quality, and reports to the ONU by a downlink control signal. The ONU sets intensity of the local oscillation light source light on the basis of the downlink control signal.;COPYRIGHT: (C)2015,JPO&INPIT
