Problems solved by technology
[0004] The above technology does not support fiber connection verification at a single site because many fiber connections depend on the optical power of the upstream site. It cannot support fiber connection inspection when the site is deployed at the beginning, and the fiber connection is correct but the quality of the fiber connection is poor. The situation cannot be detected, which affects the accuracy of detection

Embodiment Construction
[0058] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0059] The present invention relates to optical communication technology. Different cities communicate with each other by deploying stations. see figure 1 , which is a schematic diagram of a multi-site network connection provided by the present invention. Wherein, site A, site B, site C, site D, site E, site F, and site G are deployed between city 1 and city 2. The sites are connected by optical fibers to realize the transmission of optical signals.
[0060] The station involved in the present invention refers to the combination of one network element at the same location or multiple network elements connected by optical fibers and network cables capable of communicating to form a station. For example, consider multiple NEs in the ...

The invention discloses a continuous fiber detecting method, and belongs to the field of the optical communication technology. The method is applied to one site; at least a fiber is connected between an outbound port and an inbound port; and the side includes at least one light emitting element. The method includes the following method that: a path which at least includes a sending terminal single board and a receiving terminal single board; according to a continuous fiber relationship, a cross is created and attenuation regulation is carried out to make light pass through the path; attenuation on the path is adjusted, and whether the light passes through an entrance of the receiving terminal single boar is judged; if no light passes through the entrance, the wrong continuous fiber in the path is determined; and if the light passes through the entrance, a theoretical light energy change value and an actual light energy change value of the path are calculated, and according to a difference therebetween, a quality of the continuous fiber in the path is determined. In the invention, the continuous fiber quality detection and the single site continuous fiber detection are realized.
Description
technical field [0001] The invention relates to the technical field of optical communication, in particular to a fiber connection detection method and device. Background technique [0002] A WDM network refers to an optical network that adopts the transmission principle of Wavelength Division Multiplexing (English: Wavelength Division Multiplexing, abbreviation: WDM). In a WDM network, signals are finally transmitted in the form of optical signals. To transmit services from City 1 to City 2, sites must be deployed in City 1, City 2, and other passing cities. After the site deployment is complete, the sites are connected through fibers and cables. [0003] Due to the intricate fiber connections in the site, it is inevitable that mistakes will be made when manually connecting fibers according to the drawings during site deployment, and unqualified fibers may also be used. It is very difficult and heavy workload to find these errors by manual investigation. At present, there i...
