The method includes: receiving capability information that is sent by an ONU by using a first preamble; calculating a tap coefficient based on the received first preamble if the capability information indicates that the ONU has an equalization capability; sending the tap coefficient to the ONU, where the ONU updates a tap coefficient of a first equalizer in the ONU based on the received tap coefficient, and when subsequently sending upstream data, sends, by using a second preamble, the upstream data equalized by using the first equalizer, and a length of the second preamble is less than a length of the first preamble; receiving the upstream data; and equalizing the received upstream data based on the second preamble by using a second equalizer in an OLT. In this way, upstream overheads can be reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Upstream data equalization method, apparatus, and system cross-reference to related applications","description":"Embodiments relate to the field of PON technologies, and provide a method, apparatus, and system.
