Title:
OPTICAL CABLE AND OPTICAL-CABLE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/004362
Kind Code:
A1
Abstract:
An optical cable according to the present disclosure includes a plurality of optical fiber units. Each of the optical fiber units has a plurality of intermittently connected optical fiber tapes. In a cross-section, at least one of the optical fiber units is characterized in that, assuming that the midpoints of optical fibers at two ends of the optical fiber tapes are M, the centers of gravity of the optical fiber tapes are G, vectors in which the initial points are the midpoints M and the terminal points are the centers of gravity G are vectors MG, and a composite vector of the vectors MG of the respective optical fiber tapes is a vector GU, the length of the vector GU is less than the maximum length of the plurality of vectors MG of the optical fiber tapes.
