System and method for supervising optical network units

Abstract

The invention provides a supervision system and a supervision method of optical network units. The supervision system comprises at least one optical network unit and supervision equipment, wherein the optical network unit can acquire messages containing command information from optical line terminal, modify states corresponding to the optical network unit according to the command information, encapsulate the command information and the modified states corresponding to the optical network unit into encapsulation format suitable for Ethernet transmission, and send the encapsulation format to the supervision equipment via Ethernet; the supervision equipment sends the command information transmitted by the optical network unit and the correspondingly modified states to technical staff, so that the technical staff can supervise the command information received by the optical network unit and the corresponding modified states in the optical network unit. With the supervision system and the supervision method, the problem that passive optical network is transparent outwardly and cannot be supervised from outside can be solved.

Description

technical field [0001] The invention relates to a supervision scheme of a passive optical network, in particular to a system and a supervision method for supervising an optical network unit. Background technique [0002] In the passive optical network system, the optical line terminal (OLT) installed in the central control station can configure the optical network unit (ONU) through the message carrying instruction information, so as to perform different service transmissions. The above messages include: OAM (Operation Administration and Maintenance, operation, management and maintenance messages or OMCI (ONT Management and Control Interface, ONT management and control interface) messages, etc. ONU can change itself according to the instruction information in the message The state of the corresponding section. [0003] In order to be able to monitor the working conditions of ONUs, a variety of state monitoring for ONUs has been developed in China, mainly focusing on self-mo...
