Title:
OPTICAL FIBER RIBBON
Document Type and Number:
WIPO Patent Application WO/2023/219105
Kind Code:
A1
Abstract:
An optical fiber ribbon (1A) comprises a plurality of optical fibers (11) arranged in parallel to a direction orthogonal to the longitudinal direction thereof. In at least a portion of the plurality of optical fibers (11), a plurality of connecting parts (21a) that connect the optical fibers (11) adjacent to each other are provided intermittently in the longitudinal direction. Each of the connecting parts (21a) is configured such that tear stress that occurs when being torn in the longitudinal direction exhibits a plurality of peaks. The tear stress exhibits a first peak (PA1) indicating the greatest tear stress, and a second peak (PA2) indicating a tear stress different from the greatest tear stress. The tear stress at the first peak (PA1) is at least 0.01 N, and the tear stress at the second peak (PA2) is at least 50% of the tear stress at the first peak (PA1).
