Abstract
Embodiments of the present invention disclose a method for switching a modulation format of a passive optical network, an apparatus, and a system. The method includes: separately delivering, by an OLT, a registration message to an optical network unit in all supported upstream modulation formats and/or downstream modulation formats; receiving, by the OLT, a first message reported by the optical network unit, where the first message includes an upstream modulation format capability and/or a downstream modulation format capability; and determining, by the OLT, a target upstream modulation format and/or a target downstream modulation format of the optical network unit according to the first message, and instructing the optical network unit to switch to the target upstream modulation format and/or the target downstream modulation format. Therefore, in a PON system that supports a plurality of modulation formats, a modulation format reporting capability of the ONU is improved.
