Abstract: The present application discloses a method, a system and a related device for transmitting an OMCI message. In the method, an optical line terminal device sends configuration information to an optical network terminal device, where the configuration information is configured to instruct the optical network terminal device to configure a multicast port on the optical network terminal device to an enabled status so as to establish a multicast channel. The optical line terminal device sends an OMCI message that includes multicast information to the optical network terminal device through the multicast channel, where the multicast information includes a multicast port identifier and the multicast port identifier is configured to reflect a mapping between the OMCI message and the multicast port.
