Precision-Engineered for Safe Indoor DeploymentsYuhong’s Butterfly Fiber Optic Cable is engineered for high-density environments where safety, flexibility, and optical performance converge. The use of G657A1 and G657A2 bend-insensitive fibers enables exceptional performance in compact and tight-routing spaces, making this cable the ideal solution for FTTH (Fiber to the Home) and indoor distribution networks. The inclusion of a Low Smoke Zero Halogen (LS0H) sheath ensures flame retardance and minimal emission of toxic gases during combustion—critical for residential, office, or public building installations. Whether routed along baseboards or corners, this fiber optic cable maintains signal integrity even under mechanical stress.Reinforced Internal Structure with Metal Strength MemberInside its slim, butterfly-shaped profile, the cable is built with a central metal strength member that delivers robust tension resistance and stability during installation. This reinforcement ensures longevity and resilience, especially when cables are laid through walls or risers where pulling and stress are common. Additionally, the precision alignment of two parallel optical fibers within the flat geometry ensures consistent signal transmission with minimal attenuation. Its compact structure not only supports space-saving but also contributes to easy handling, stripping, and connectorization—traits essential for fiber optic internet cable deployments in constrained environments.Tailored for Indoor Optical Access SystemsDesigned for seamless integration into indoor access networks, this cable ensures compatibility with standard fiber management hardware, wall outlets, and termination boxes. The LS0H outer jacket ensures compliance with strict building codes while offering abrasion resistance and environmental shielding. With both G657A1 and G657A2 variants, the product provides adaptability for different bend radii and performance needs. This makes Yuhong’s Butterfly Fiber Optic Cable a practical choice for modern smart buildings, supporting high-speed data, voice, and video transmission without compromising on safety or performance. Product AdvantagesFlat Butterfly Structure with Dual Fiber PathwaysUnlike traditional round or loose tube cables, the butterfly structure provides dual, precisely aligned fiber optic cable pathways that maintain geometry and reduce microbending loss. This flat profile not only facilitates easy termination with standard connectors but also minimizes space consumption during installation in wall conduits or narrow trays. The fixed core layout prevents core misalignment during flexing, enhancing long-term optical stability, which is essential for in-building networks with numerous directional changes.Metal Strength Rod for Mechanical StabilityAt the heart of the cable lies a metal strength member designed to absorb tensile loads and stabilize the internal structure. This reinforcement allows safe pulling during installation without risk of core damage or fiber deformation. Especially valuable for fiber optic cable supplier installations across multi-story buildings or surface-mounted layouts, the metal core extends service life by reducing the risk of internal breaks caused by bending, stretching, or impact.LS0H Jacket for Flame-Retardant, Low-Emission EnvironmentsThe LS0H (Low Smoke Zero Halogen) outer jacket is engineered to meet modern fire safety standards. In case of a fire event, it releases negligible toxic gas and produces minimal smoke, safeguarding occupants and equipment. This property makes the cable suitable for confined spaces like data centers, apartments, and hospitals. As fiber optic cable manufacturers increasingly address sustainability and compliance, this material choice enhances both operational safety and environmental responsibility. Use ScenariosFTTH Network Rollouts in Urban Apartment ComplexesNetwork providers deploying fiber optic internet cable solutions in densely populated residential areas often face routing challenges through tight shafts and wall corners. Yuhong’s Butterfly Fiber Optic Cable, with its G657A2 variant, excels in tight bend conditions and can be installed along baseboards and stairwell edges without compromising signal quality. The LS0H sheath ensures adherence to fire regulations, essential in multi-dwelling units where resident safety is a priority during indoor routing.Structured Cabling in Office Floor RenovationsTelecom integrators managing IT infrastructure for renovated office floors benefit from the cable’s flat shape and reinforced core. The dual-fiber geometry allows direct connection from building entry points to wall outlets without extensive splicing. The fiber optic cable’s flexibility reduces the need for excessive junctions or slack management, improving both speed and reliability of deployment in environments where minimal disruption is key.Healthcare Facilities Requiring Low-Toxicity MaterialsIn hospitals or medical labs where fire risk and air quality are critical, network engineers choose Yuhong’s LS0H butterfly cable for its smoke-suppressed jacket and bend-insensitive G657A1 fibers. These characteristics ensure safe operation of fiber optic cable infrastructure in MRI rooms, nurse stations, and surgical control centers—delivering uninterrupted connectivity for essential systems while aligning with strict building codes and health standards.
