Abstract: The system includes an optical line terminal, a cloud server and an optical network terminal, wherein, the optical line terminal includes a part of management entities supported by the OMCI protocol, the part of management entities is associated with device information of the optical line terminal, the cloud server supports virtual OMCI, and the cloud server includes another part of management entities supported by the OMCI protocol. According to the scheme of the disclosure, by retaining a part of MEs supported by the OMCI protocol which is associated with the device information of OLT in OLT, and deploying another part of MEs supported by the OMCI protocol in the cloud server, it can reduce or avoid the dependency of the vOMCI on the OLT device while the vOMCI is realized to reduce the complexity of the OLT device and improve the flexibility of deploying the OMCI protocol stack of different service providers.
