System and method for online monitoring of color ring points of optical fiber

Abstract

The invention relates to the technical field of optical fiber detection, in particular to a system and method for online monitoring of a color ring point of an optical fiber. A color ring point monitoring device utilizes the stroboscopic principle, light rays which flash rapidly through frequency directly irradiate on the running looping optical fiber, when the flashing frequency of a light sourceis synchronous with the looping frequency, the distribution condition of color ring points on the high-speed moving optical fiber can be easily observed by using the persistence of vision of eyes, the real-time monitoring of the looping process is realized, the problem of ring leakage or ring running can be found in advance, and the unqualified color ring fiber is prevented from flowing into thenext process, so that the production cost is improved.

Description

technical field [0001] The invention relates to the technical field of optical fiber detection, and relates to an on-line monitoring system and method for optical fiber ringing and color ring points. Background technique [0002] In the process of optical cable production and laying, in order to meet the communication performance, it is necessary to test, track, and monitor the performance indicators of each optical fiber at all times, and there are different types of optical fibers in the fusion process of some optical cables. In order to detect, track, and weld optical fibers more simply and conveniently, It is therefore crucial to differentiate between fibers. [0003] At present, in the optical cable standard, the full color spectrum is used to distinguish the optical fibers in the large-core optical cable. When the number of optical fiber cores in the same optical cable exceeds 12 cores, black ink is continuously sprayed on the bare optical fiber at a certain interval. ...

[0003] At present, in the optical cable standard, the full color spectrum is used to distinguish the optical fibers in the large-core optical cable. When the number of optical fiber cores in the same optical cable exceeds 12 cores, black ink is continuously sprayed on the bare optical fiber at a certain interval. However, in actual During the production process, we found that due to the fast speed of the ring machine and the small color ring points, the production process cannot identify whether the color ring points are normal or whether there are missing points or rings.
