The method includes that MEPs are established respectively at the OLT interface of an OLT and the network interfaces of a plurality of gateways to form an access OAM domain; and in the access OAM domain, an Ethernet OAM message is sent between the MEP of the OLT and the MEP of the corresponding gateway to test the continuity of a service link between the OLT interface of the OLT and the corresponding gateway. Thus, the related functions of the ONU are transferred to the OLT, the OLT simulates the UNI of the ONU to enable the Ethernet OAM function and monitors in real time or manually checks the status of the service link from the gateway to the OLT, so that a failure point of an internal service layer of an access node is determined, the cost on the ONU device and the system configuration and administration cost are reduced greatly, and the Ethernet maintenance requirement of an optical access node in the TR101VLAN architecture is met."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for link check in passive optical network","description":"A method and an apparatus for checking a PON link are provided.
