Outdoor Stranded Armored Optical Cable

Conventional central tube optical cables are limited by small core capacity and cannot meet large-bandwidth trunk network expansion demands for urban and industrial projects. Ordinary non-armored stranded fibers lack rigid mechanical protection, vulnerable to rodent biting, rock extrusion and construction mechanical damage during direct burial laying, easily causing fiber breakage and network paralysis. Low-grade stranded cables adopt incomplete water-blocking structures, prone to longitudinal water penetration, hydrogen aging and signal attenuation after long-term underground operation. Common outdoor cables have insufficient tensile strength, unable to adapt to long-span aerial laying and complex terrain stress, resulting in core displacement and performance degradation. In municipal backbone, highway communication and large-scale park trunk networking scenarios, ordinary lightweight cables suffer from high failure rates and short service life. The Outdoor Stranded Armored Optical Cable thoroughly solves the above industry pain points. Adopting professional SZ stranded loose tube layered structure, multiple independent loose tubes are evenly stranded around the central strength member, supporting core capacity expansion up to 288 cores to meet large-bandwidth trunk transmission demands. Each loose tube is filled with waterproof jelly, matched with overall cable core water-blocking material to achieve full-sealed waterproof and moisture-proof protection. The outer corrugated steel tape armor forms a rigid protective barrier, effectively resisting external pressure, impact and rodent damage. High-strength central tensile member bears long-term laying tension and environmental stress, avoiding fiber core damage. High-quality low-attenuation optical fiber ensures stable long-distance signal transmission. The upgraded high-density PE outer jacket features UV resistance and weather aging resistance, adapting to all-weather harsh outdoor environments and realizing decades of maintenance-free stable operation.

This heavy-duty stranded armored fiber cable supports diversified personalized customization for municipal telecom backbone networking, highway communication engineering, industrial park large-capacity trunk wiring, remote cross-region signal transmission and smart city communication construction. SZ stranded loose tube layered structure realizes large-core capacity expansion, fully meeting high-bandwidth network upgrade and multi-service transmission demands. Corrugated steel tape armored layer provides excellent anti-crush, anti-impact and anti-rodent performance, solving common mechanical damage problems in buried engineering. Full jelly-filled integrated water-blocking system completely isolates groundwater and rain penetration, preventing fiber damp attenuation and hydrogen aging. High-strength metal or non-metallic central strength member enhances overall tensile stability, adapting to long-span aerial and complex terrain laying. Standard tube & core color coding enables rapid identification, efficient splicing and convenient daily maintenance. Ultra-low attenuation optical core ensures long-distance lossless transmission with stable network latency. Industrial-grade wide-temperature design maintains stable performance in extreme cold and hot outdoor climates. According to project demands, we can customize fiber core count, single/multi-mode fiber type, steel tape/steel wire armor grade, metal/FRP tensile member and sheath material to meet refined heavy-duty outdoor communication requirements.
