Zusammenfassung:An OLT, which is a station-side apparatus in a PON system, is connected to an ONU via an optical fiber. The OLT includes: an optical receiver which receives a burst signal from an ONU; a burst header detection unit which detects a certain delimiter pattern included in a received burst signal so as to establish synchronization of the burst signal; and a control unit which allows the burst header detection unit to perform detection of a delimiter pattern during a predicted reception period of a burst signal.
