Novel Optical Fiber Cable with Small Cable Diameter Employing Rollable 20-Fiber Ribbons

摘要

This letter proposes novel optical fiber cables with extremely small cable diameter that employs rollable 20-fiber ribbons, which will improve fiber ribbon and cable productivity compared with optical fiber cable employing rollable 4-fiber ribbons. We fabricated the cables and investigated its feasibility in terms of high-count compactness, cable productivity, fiber strain induced by cable bending, optical loss characteristics and capacity for mass splicing. As a result, we confirmed the excellence of these cables and their fiber splicing workability.
