Method, device and system for repeater management

[1] This application claims priority to Chinese Patent Application No. 200810065539.X, entitled "Method, Apparatus and System for Repeater Management", filed on March 12, 2008, The entire contents of this application are incorporated herein by reference.

[2] Technical field

[3] The present invention relates to optical network technology in the field of communications, and in particular to a method, device and system for relay management.

[4] Background of the invention

[5] Currently, GPON/EPON (Gigabit-Capable Passive Optical Network/Ethernet Passive)

Optical

Network) is a new generation of broadband passive optical integrated access technology. Traditional GP0N/EP0N systems consist of Optical Line Terminal (OLT), Optical Distribute Network (ODN) and Optical Network Unit (ONU, Optical Network).

Units, the OLT is connected to an ODN; the ODN broadcasts the downlink data of the optical line unit to each ONU. Similarly, the ODN transmits the uplink data of the ONU to the optical line unit through convergence. Due to the limitation of ODN line attenuation and the output optical power of the existing laser transmitter, receiver sensitivity and other factors, EPON/GPON currently only supports the largest ODN fiber length of 20Km.

[6] When PON applications are in a relatively sparsely populated area, in order to reduce operating costs, PON systems are required.

The solution proposed by the prior art is to add an Extender to the existing ODN system to extend the length of the fiber between the OLT and the ONU, and to increase the service coverage of the office where the OLT is located. This kind of PON system is called long-distance PON in the industry (the distance between the LR-PON OLT and the repeater can reach 40Km, and the distance between the repeater and the ONU can reach 20km, that is, after the introduction of the repeater, The coverage of LR-PON can reach 60Km.

[7] OMCI is a configuration transmission channel defined in the GPON standard.

The ONU registers with the OLT to establish an OMCI channel between the two. OMCI is a master-slave management protocol, OL T is the master device, ONU is the slave device, and the OLT controls multiple ONUs connected below it through the OMCI channel. Ready.

[8] The signal repeater can be realized by means of optical (Electronic-Optical) or optical amplifier (OA, Optical Amplifier).

Repeaters Extend multiple OEO/OAs in the Extender and relay them to multiple OLTs. The ONU integrated in the repeater is registered on a 0LT, and monitors the working status of multiple 0E0/0As. In the allocated inter-segment, the collected parameters of multiple 0E0/0A are reported to the 0LT, and the pair is implemented. Extender management. 0NU At any moment, it will only be registered on a 0LT, so when it is associated with 0E0/0A associated with the integrated 0NU, or the corresponding backbone fiber, or the P0N fault with the integrated 0NU communication, the 0NU cannot be associated with it. 0LT communication, and then the 0LT system cannot control and manage the Extender, and the reliability of the system cannot be guaranteed.

[Embodiment 4] Embodiment 4 of the present invention provides a method for implementing an integrated management repeater. As shown in FIG. 4, it is a schematic flowchart of a method provided by Embodiment 4 of the present invention. In FIG. 4:

[61] In step 402, the integrated optical network unit 1 in the repeater sends request registration information to the optical line terminal, and after receiving the message, the optical line terminal starts the activation process of the integrated optical network unit 1, and The integrated optical network unit 1 in the repeater is specially labeled to indicate that it is an integrated optical network unit for integrated management.

The integrated optical network unit 1 in the repeater is associated with the extension module 1 via a switching unit. The association mentioned here does not mean that the integrated optical network unit 1 and one of the extension modules have communication, and the integrated optical network unit 1 Because all extension modules are monitored for operation, they communicate with all extension modules. Since the integrated optical network unit 1 can only be registered on one optical line terminal at any moment, the monitoring information can only be uploaded to an optical line terminal through an extension module, so that the integrated optical network unit 1 is associated with an extension module.

[83] Alternatively, the optical line termination system can set the inter-turn value, which can be set according to the site conditions. When the optical line terminal does not receive the message of the integrated optical network unit 1 in the preset time zone, the optical line terminal first maintains the association relationship with the corresponding extension module, and attempts to re-register, if not, the The optical line termination system determines that the connection between the extension module and the optical line terminal is broken.

[94] The certain parameters are higher or lower than the threshold value 设有 provided in the integrated optical network unit 1. Specifically, the thresholds of the responses may be respectively set according to specific parameters, and the parameters may be respectively determined according to the corresponding thresholds. After the parameters exceed the set threshold, the integrated optical network unit 1 determines that the connection between the extension module and the optical line terminal is no longer reliable. [95] Alternatively, the integrated optical network unit 1 can be set by setting the inter-turn value, which can be set according to the situation on site.
