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.

Claim (Index 19):
The optical network unit according to  claim 16 , wherein\n the processing unit is further configured to: determine whether the acknowledgement grant message delivered by the optical line terminal is received within a preset time after the second message is reported, and if the acknowledgement grant message delivered by the optical line terminal is not received within the preset time, switch the optical network unit back to a source upstream modulation format and/or a source downstream modulation format.
