Description

ODN connection relation determining method and device

Technical Field

The invention relates to the technical field of optical fiber communication, in particular to a method and a device for determining an ODN connection relation.

Background

With The need for communication development, various Fiber optic communication technologies are emerging in succession, namely FTTx (Fiber To The x, x ═ H for Home, P for Premises, C for curr, N for Node or neighbor borwood, O for Office, SA for Service Area and B for Building, where FTTH Fiber To The Home, FTTP Fiber To The Premises, FTTC Fiber To The Curb or The cell, FTTN Fiber To The Node, FTTO Fiber To The Office, FTTSA Fiber To The Service Area, and FTTB Fiber To The Building). In the development of FTTx, an access layer needs to create an ODN (Optical Distribution Network), the Network construction cost of the ODN is high, and the long-term development of a broadband Network needs to be supported, so that the requirements for ODN construction, operation and maintenance are higher and higher, and the ODN Network connection relationship needs to be combed on the premise of not changing the ODN passive Network characteristics, so as to ensure the accuracy of ODN Network resources.

The traditional ODN network connection relationship is combed generally by adopting a red light pen mode, namely, a constructor pulls down one end A of a jump fiber in ODN equipment and uses the red light pen to emit red light, other constructors search the red light at a possible opposite end port, if finding that a certain port B emits the red light, the A and the B are considered as a pair, so that the connection relationship of the jump fiber is determined, and a paper label is used for recording and adhering the record on the jump fiber port. However, the red light pen mode requires cooperation of multiple persons to determine the connection relationship of the patch fibers, and is low in efficiency especially when the number of ports of the ODN device is large. Moreover, because the luminous power of the red light pen is low, the method is only suitable for carding the jump fibers in the same cabinet, if the method is used for carding the optical fiber connection relationship between cabinets, a plurality of adjacent cabinets are required to search the opposite end, and the feasibility is low. Meanwhile, the paper label is easy to damage, the recorded content is easy to make mistakes due to human factors, and the reliability is low.

Optionally, please refer to fig. 3, which is a schematic structural diagram of a handheld ONU according to an embodiment of the present invention, as shown in fig. 3, the handheld ONU is plugged with a jump fiber, and then can be connected to an ODN port in the iODN device through a connector of the jump fiber, and an electronic tag is fixed on the connector of the jump fiber, that is, an optical fiber connector, and the electronic tag can be identified by the iODN device or the iODN device construction tool. The electronic tag and the optical fiber connector can be inserted into the iODN device at the same time, or can be inserted in two steps (the optical fiber connector is inserted first, and then the electronic tag is inserted, or the electronic tag is inserted first, and then the optical fiber connector is inserted). The electronic tag stores a special serial number, and after the iODN equipment is inserted, the serial number can be recognized by the iODN equipment or an iODN equipment construction tool, so that the identity of the electronic tag is determined. When the electronic tag is inserted, the iODN device or the iODN device construction tool may automatically read the electronic tag on the optical fiber connector, and obtain an ODN port number corresponding to an insertion position of the electronic tag, where the ODN port number may uniquely identify position information of the port in the iODN device, for example, the ODN port number is a frame number, a board number, and a slot number, such as: 1-2-10(1 frame, 2 trays, 10 ports).

And the iODN network manager performs association pairing on the OLT port number and the iODF port number, namely, the analyzed OLT port number is used as the alarm OLT port number corresponding to the ODN port corresponding to the currently acquired iODF port number. After the warning OLT port number and the idodf port number corresponding to the iODF port are obtained, the iODN webmaster may also return a port information obtaining success message, and may display the success message on a construction tool used for supplying power and managing the iODN device, so as to prompt resource combing of the next iODF port.
