OPTICAL NETWORK UNIT DETECTION METHOD AND DEVICE, AND PASSIVE OPTICAL NETWORK SYSTEM.

摘要

Disclosed are an ONU detection method and device and a passive optical network system. The method includes: detecting the identification code of an ONU within an open uplink window period or a blank timeslot; and according to the identification code of the ONU, determining the ONU corresponding to the identification code of the ONU as a rogue ONU. Also provided are a corresponding device and a passive optical network system. Rapid and highly efficient detection is realized and the rogue ONU is determined in the passive optical network system, reducing the effects on uplink services.
