A method and a device for transmitting parameter granularity are disclosed. The method includes: an Optical Line Terminal (OLT) transmits parameter granularity to an Optical Network Unit (ONU) through a Ranging GRANT message, or an OLT transmits parameter granularity to an ONU through a profile Physical Layer Operation, Administration and Maintenance (PLOAM) message, or parameter granularity is set to an ONU through a SET operation of an Optical Network Terminal Management Control Interface (OMCI); and the ONU determines a location of an uplink bandwidth allocated from the OLT to the ONU in an uplink frame according to the parameter granularity and a parameter to which the parameter granularity corresponds in an allocation structure. With the disclosure, the granularity of an adopted parameter can be notified to different ONUs when the OLT allocates an uplink bandwidth to the different ONUs. |
