Method for managing optical network unit onu, apparatus, and system

A network device, comprising:

• a transceiver, configured to send a message for obtaining a management mode supported by an optical network unit ONU);
• and receive a management mode sent by the ONU;
• and send the selected management mode to the ONU;
• and
• a processor, configured to:
• select a management mode for the ONU based on the management mode supported by the ONU;
• send the selected management mode to the ONU by using the transceiver, wherein the management mode supported by the ONU comprises one or more of an optical network unit management and control interface (OMCI) mode, an operation, administration, and maintenance (OAM) management mode, a network configuration protocol (NETCONF) management mode, a technical report 069 (TR069) management mode, or a simple network management (SNMP) management mode.

A passive optical network (PON) system, comprising:

• an optical line terminal (OLT) and an optical network unit (ONU), wherein the OLT is connected to the ONU by using an optical distribution network (ODN), and the OLT comprises:
• a transceiver, configured to send a message for obtaining a management mode supported by an optical network unit (ONU);
• and receive a management mode sent by the ONU;
• and send the selected management mode to the ONU;
• and
• a processor, configured to:
• select a management mode for the ONU based on the management mode supported by the ONU;
• send the selected management mode to the ONU by using the transceiver, wherein the management mode supported by the ONU comprises one or more of an optical network unit management and control interface (OMCI) mode, an operation, administration, and maintenance (OAM) management mode, a network configuration protocol (NETCONF) management mode, a technical report 069 (TR069) management mode, or a simple network management (SNMP) management mode.
