STATION APPARATUS AND PON SYSTEM UPLINK COMMUNICATION METHOD

摘要

A PON system composed of a terminal connected through an optical fiber (5) and a station apparatus (1) for managing the terminal. A control signal processing section (104) gives the terminal a grant of uplink communication. A next-reception burst judging section (106) stores the rate of transmission of a plurality of uplinks used by the terminal and specifies the time at which the next uplink signal is received under the grant and the transmission rate. A light-receiving section (109) and a PON receiving section (107) associate the reception function with the specified transmission rate in concert with the time, and thus the signal is received in this state.
