Problems solved by technology

[0005] When the existing Combo-PON optical module is in use, although the 10G GPON and GPONMAC units in the Combo-PON optical module can generate respective alarms independently, such as the backbone LOS alarm, the LOSi alarm (the optical signal of the ONU is lost), etc., however, as A unified and integrated Combo-PON optical module has no LOS alarm function, which makes it difficult for users to manage and maintain the Combo-PON optical module

Embodiment 1

[0051] Before S1, the following steps are also included: Authorize the ONU connected to the Combo-PON optical module: the GPON MAC unit or 10G GPON MAC unit of the Combo-PON optical module periodically passes through the PLOAM (Physical Layer OAM, Operations Administration and Maintenance , physical layer operation management and maintenance) message or OMCI (ONUManagement and Control Interface, Optical Network Unit Management Control Interface) message to obtain the own information of the access ONU; the service line card obtains the ability to access the ONU through the OMCI message, and sends the ONU The capability is adapted to the capability set template to obtain the type of the ONU. Determine whether the ONU's own information is legal, if so, authorize the ONU, otherwise not authorize.

[0052] The authorized ONU will be displayed in the graphical management interface. On the graphical management interface, the COMBO-PON optical module is managed as an object. The singl...

Embodiment 2

[0054] On the basis of Embodiment 1, the criterion for judging the legality of the ONU's own information is: obtain the ONU's own information, which is the same as the corresponding authorization information in the service line card authorization table, and the authorization information in the service line card authorization table is entered in advance by the user (Promptly indicate which are legal ONUs, the user does not need to care about or know the type of ONU); self information is at least one of the SN (physical serial number), user password and LOID (logical serial number) of the ONU.

Embodiment 3

[0056] The process of S1 includes:

[0057] S101: When detecting that a GPON MAC unit or a 10G GPON MAC unit generates an LOS alarm, determine whether another MAC unit generates an LOS alarm, if so, go to S103, otherwise go to S102.

[0058] S102: Determine whether another MAC unit has a corresponding ONU access (only authorized and activated ONUs can access), if so, no LOS alarm of the Combo-PON is generated, and S1 ends; otherwise, S103 is turned.

[0059] S103: A Combo-PON LOS alarm is generated, and S1 ends.

Abstract

The invention discloses a Combo-PON LOS alarm method and system, and relates to the field of upgrading and transformation of GPON and 10G GPON. The steps of the method are: Combo-PON LOS alarm generation process: when both the GPON MAC unit and the 10G GPON MAC unit of the Combo-PON optical module generate an LOS alarm, the Combo-PON LOS alarm is generated; when the GPON MAC unit or the 10G When the GPON MAC unit generates an LOS alarm, and the MAC unit that does not generate the alarm does not have a corresponding ONU access, a Combo-PON LOS alarm is generated; the Combo-PON LOS alarm end process: When the GPON MAC unit or 10G GPON MAC unit detects When the ONU is connected, the LOS alarm of the Combo-PON is ended. The present invention can realize the LOS alarm for the Combo-PON optical module, and is convenient for users to manage and maintain the Combo-PON optical module.

Description

technical field [0001] The invention relates to the field of upgrading and transforming a GPON (Gigabit-Capable PON, gigabit passive optical network) access system to 10GGPON, and specifically relates to a Combo-PON LOS alarm method and system. Background technique [0002] During the evolution or upgrade of the GPON (Gigabit-Capable PON, Gigabit Passive Optical Network) access system to 10G GPON, there will inevitably be scenarios where GPON and 10G GPON access coexist. The coexistence of traditional GPON and 10G GPON is: using external wavelength division multiplexing devices to share and reuse ODN networks. When external WDM devices are installed, the equipment room needs to add 10G GPON line cards, OLT sub-frames, and WDM device sub-frames, and the optical line jumper needs to be modified at the OLT end. For details, see: figure 1 As shown, the MAC (Media Access Control, medium access control layer) unit and GPON MAC unit of 10G GPON are connected to the ODN separately,...
