Skeleton-type optical cable butterfly shape

A skeleton-type butterfly-shaped optical cable features a butterfly-shaped sheath with a central skeleton that organizes and protects optical fiber ribbons, offering stable performance and easy maintenance.Structure and DesignSkeleton-type butterfly optical cables have a cross-sectional shape resembling a butterfly, with two wings extending symmetrically from a central skeleton. The skeleton is positioned at the center of the sheath and serves as a structural backbone, providing mechanical support and protecting the optical fibers from thermal and mechanical damage during production and installation . The cable typically includes:First reinforcement components: Positioned symmetrically on the wings of the sheath to enhance tensile strength .Second reinforcement component: Located at the center of the skeleton for additional support .Protective layer: Wraps the skeleton to shield fibers from environmental stress .Skeleton slots: Spaces within the skeleton where dispersive optical fiber ribbons are placed, keeping fibers organized and reducing the risk of damage .Tearing ports: Symmetrically arranged along the skeleton to allow easy stripping of the cable without damaging the fibers .AdvantagesStable and reliable performance: The skeleton structure minimizes fiber deformation and signal loss during handling and installation .Reduced thermal damage: Direct contact between fibers and the sheath is minimized, preventing heat-related fiber damage during extrusion .Easy maintenance: The skeleton allows selective access to fiber ribbons without stripping the entire cable, reducing future maintenance risks .Mechanical strength: Reinforcement components and the skeleton provide high tensile strength, making the cable suitable for pipelines, overhead, and direct burial applications .Compact and efficient design: The butterfly shape allows for a small outer diameter while maintaining fiber protection and organization .ApplicationsSkeleton-type butterfly optical cables are widely used in telecommunication networks, including FTTH (Fiber to the Home), 5G infrastructure, and other high-density fiber deployments. Their design supports easy installation in confined spaces, hybrid electro-optical applications, and long-span outdoor deployments . In summary, the skeleton-type butterfly-shaped optical cable combines a butterfly-shaped sheath with a central skeleton to provide mechanical protection, organized fiber placement, and simplified maintenance, making it a reliable choice for modern fiber optic networks .
