  • Patent number: 10439724
    Abstract: A passive optical network (PON) includes a first optical line terminal (OLT), a second OLT, and an optical network unit (ONU). The first OLT sends an equalization delay change message to the ONU, wherein the equalization delay change message includes an equalization delay, an upstream channel ID and a downstream channel ID corresponding to the equalization delay. The ONU receives the equalization delay change message. When the ONU tunes from the first OLT to the second OLT, the ONU obtains the equalization delay for upstream transmission according to the upstream channel ID and the downstream channel ID.
