Communication optical fiber port management system based on color identification

Abstract

The invention discloses a communication optical fiber port management system based on color recognition, which comprises a light source, a single-mode optical fiber, a polarization module, a polarization maintaining optical fiber, a multimode optical fiber, an optical path fixing module and a color recognition module arranged on the optical path fixing module which are connected in sequence, a light source is input to a light path, passes through a single-mode optical fiber and is divided into two beams of vertical polarized light through a polarization module, the polarized light passes through two polarization maintaining optical fibers connected with the polarization module respectively and interferes at the tail end of a multimode optical fiber, and a plurality of speckle images are formed through recognition of a color recognition module by adjusting a light path fixing module. Extracting a pixel center from the connected domain corresponding to each speckle region, determining an RGB value of each pixel according to the pixel center to obtain a sample speckle image, inputting the sample speckle image into a pre-trained neural network, extracting feature information of the sample speckle image by a convolutional layer of the neural network, and outputting the feature information of the sample speckle image; and the precision and the working efficiency of optical fiber port detection are improved.

Description

technical field [0001] The invention relates to the technical field of communication engineering, in particular to a communication optical fiber port management system based on color recognition. Background technique [0002] With the explosive growth of IP services and the increasingly openness of my country's telecommunication operation market, the industry regards the construction of an IP service-oriented telecommunication infrastructure network as their network construction focus. At present, the technical solution of the access layer is mainly based on the optical fiber access network. For the appearance of the city, it is often necessary to lay fiber optic networks underground. With the continuous development of fiber optic network technology, from the previous fiber-to-community, fiber-to-building, to the current fiber-to-home, the number of fiber-optic connections continues to increase. Fiber distribution networks are becoming denser and denser. [0003] A large n...

Problems solved by technology

[0003] A large number of optical fiber wiring brings a problem: the wrong connection between the optical fiber and the optical fiber port causes the line to be blocked, and it is difficult to maintain in practice

At present, the routing and connection of the optical distribution network (ODN) is completely dependent on manual operation. In addition, when the existing ODN is connected to the optical fiber port, the optical fiber port of the ODN can only be marked with a paper label to indicate the connection between the optical fiber and the ODN port. connection relationship

When it is necessary to inspect the optical fiber link of the ODN, the engineers manually inspect the optical fiber ports and their connection status of the optical fiber link one by one according to the paper label. The inspection process is cumbersome and error-prone, and the optical fiber inspection process is prone to damage. , so that the accuracy of fiber detection is low
