Method and apparatus for determining ODN connection relation

Abstract

An embodiment of the invention discloses a method and apparatus for determining an optical distribution network (ODN) connection relation. The method comprises the steps of obtaining an alarm optical line terminal (OLT) port number corresponding to each ODN port of an ODN device, wherein the alarm OLT port number corresponding to each ODN port is an OLT port number of the port generating an alarm at the OLT side when a detection tool is inserted to the ODN port; and determining the ODN ports having the same alarm OLT port number as the ODN ports in a connection relation. The invention can be used for determining the connection relation among the ports of the ODN device, and therefore can effectively organize ODN network resources.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a method and device for determining an ODN connection relationship. Background technique [0002] With the needs of communication development, various optical fiber communication technologies have appeared one after another, that is, FTTx (FiberToThex, x = HforHome, PforPremises, CforCurb, NforNodeorNeighborhood, OforOffice, SAforServiceAreaandBforBuilding, among which FTTH fiber to the home, FTTP fiber to the resident, FTTC fiber to the roadside Or 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, the access layer needs to build a new ODN (Optical Distribution Network, optical distribution network). On the premise of not changing the characteristics of the ODN passive network, it is necessary to sort out the ODN network connection relationship to ensure the acc...

Problems solved by technology

However, the method of the red light pen requires the cooperation of multiple people to complete the determination of the connection relationship of the fiber jumper, especially when there are many ports on the ODN device, the efficiency is low

Moreover, since the luminous power of the red light pen is relatively low, this method is only suitable for sorting out fiber jumpers in the same cabinet. If it is used to sort out the connection relationship between optical fibers between cabinets, it is necessary to go to multiple adjacent cabinets to find the opposite end, which is feasible. lower sex

At the same time, the paper label is easily damaged, and the recorded content is also prone to errors due to human factors, so the reliability is low
