A 48-core single-mode armored optical cable is designed for high-capacity, long-distance, and harsh-environment deployments, featuring OS2 fibers, steel armoring, and compliance with ITU-T G.652D standards.

Key Features

Fiber Type and Core Count: These cables contain 48 single-mode fibers (9/125 µm), typically compliant with ITU-T G.652D standards, ensuring low attenuation and high signal integrity for long-distance transmission . Armoring and Mechanical Protection: Armored variants include steel wire or corrugated steel tape layers, providing protection against mechanical stress, rodent damage, and harsh environmental conditions . Some models, like the Starlight SWA, feature galvanized wire armoring combined with aramid strength members for additional tensile strength . Cable Construction: Common constructions include loose-tube, gel-filled or gel-free designs, with water-swellable tapes or foam layers to prevent moisture ingress. Ribbon stacking may be used for high-density fiber arrangements, as seen in Corning SST-Ribbon cables . Environmental Suitability: These cables are suitable for direct burial, aerial, duct, and underground installations, with UV-resistant and flame-retardant jackets for outdoor and industrial applications . Standards and Compliance: Many 48-core armored cables meet OS2 single-mode specifications, RDSO approvals for railway and telecom applications, and IRS/industry standards for mechanical and environmental performance . Applications:

• Telecommunication networks for high-capacity data transmission
• Railway signaling and communication
• FTTH (Fiber-to-the-Home) and broadband networks
• Industrial automation and smart city infrastructure
• Harsh environment installations, including tunnels and direct burial Performance: These cables offer low signal attenuation, high tensile strength, and long-term reliability, making them ideal for long-distance and high-speed optical networks .
