Title:
OPTICAL FIBER RIBBON
Document Type and Number:
WIPO Patent Application WO/2023/286415
Kind Code:
A1
Abstract:
An optical fiber ribbon (1) comprises five or more optical fibers (20) and a plurality of connecting parts (10) which connect two adjacent optical fibers. The plurality of connecting parts (10) are disposed intermittently in the longitudinal direction (X direction) and in an arrangement direction (Y direction). The optical fiber ribbon has a first high density region (D1), a first low density region (S1), a second high density region (D2), and a second low density region (S2). The number density of the connecting parts (10) in the first low density region (S1) is lower than the number density of the connecting parts (10) in the first high density region (D1). The number density of the connecting parts (10) in the second low density region (S2) is lower than the number density of the connecting parts (10) in the second high density region (D2). The first low density region (S1) and the second low density region (S2) are offset in the longitudinal direction (X direction).
