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 invention provides a method and device for inspecting intermittently connected optical fiber tape, and a manufacturing method. In order to inspect an intermittent-connection-type optical fiber tape with high precision despite an increased number of cores in the intermittent-connection-type optical fiber tape. This method for inspecting an intermittent-connection-type optical fiber tape comprises: repeatedly capturing an image of an intermittent-connection-type optical fiber tape along the width direction thereof, the intermittent-connection-type optical fiber tape in which connecting partsfor connecting adjacent optical fibers are intermittently arranged, while moving the optical fiber tape in the longitudinal direction thereof, and accumulating one-dimensional images in the width direction of the optical fiber tape; and arranging the accumulated plurality of one-dimensional images in a first direction in which pixels constituting part of the primary images are arranged and a second direction orthogonal to the first direction, and creating a two-dimensional image of the optical fiber tape.

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, ...
