Problems solved by technology

However, if it is considered that a hole for laser irradiation is arranged at each joint (refer to Patent Document 2 Figure 8 ), it is expected that when the number of cores of the optical fiber ribbon increases, the arrangement (position adjustment) of the laser sensor becomes very difficult

Abstract

The present invention provides an inspection method, an inspection device, and a manufacturing method of an intermittent connection type optical fiber ribbon, which can inspect an intermittent connection type optical fiber ribbon with high precision even if the number of cores of the intermittent connection type optical fiber ribbon increases. In the intermittent connection type optical fiber ribbon inspection method of this article, the following operation is performed: while moving the intermittent connection type optical fiber ribbon intermittently arranged at the connecting portion connecting adjacent optical fibers in the longitudinal direction, the optical fiber is repeatedly photographed in the width direction. tape, accumulating the one-dimensional image of the above-mentioned width direction of the above-mentioned optical fiber ribbon; 2D image of .

Description

technical field [0001] The present invention relates to an inspection method, an inspection device and a manufacturing method of an intermittent connection type optical fiber ribbon. Background technique [0002] Patent Documents 1 to 3 describe inspection methods for inspecting optical fiber ribbons in which a plurality of optical fibers are intermittently connected in parallel (hereinafter referred to as "intermittently connected optical fiber ribbons" or simply "optical fiber ribbons"). In the inspection method described in Patent Document 1, the intermittently connected optical fiber ribbon is supported by a guide roller having a stepped portion to separate the non-connected portion of the intermittently connected optical fiber ribbon, and the edge interval, the number of edges, etc. of the intermittently connected optical fiber ribbon are measured. , to detect the abnormality of the connection part of the intermittent connection type optical fiber ribbon. In addition, ...
