Outdoor Single-mode Dual-core Fiber Optic

A single-mode dual-core outdoor fiber optic cable is designed for high-speed, long-distance data transmission in harsh outdoor environments, featuring two optical fibers, robust armoring, and weather-resistant jackets.Key FeaturesFiber Type and Mode: These cables use OS2 single-mode fibers (9/125 µm), optimized for long-distance transmission at 1310nm and 1550nm wavelengths, supporting data rates from 1G to 100G and beyond . Fiber Count: Dual-core or 2-fiber configuration allows for bidirectional communication or redundancy in outdoor networks . Armoring and Strength: Outdoor cables often include steel wire or metal armor to protect against rodents, mechanical stress, and environmental hazards. Some designs use stainless steel woven mesh or corrugated steel for dual-layer protection . Jacket Material: Jackets are typically made from TPU, LSZH, or UV-resistant polyethylene, providing waterproofing, UV resistance, abrasion resistance, and temperature tolerance from -40°C to +70°C . Mechanical Properties: These cables are engineered for high tensile strength (up to 600 N short-term), crush resistance, and minimum bend radius (15D long-term, 30D short-term), ensuring durability during installation and operation . Installation Options: Suitable for direct burial, aerial deployment, or duct installation, with some pre-terminated cables featuring pulling eyes or uniboot connectors for easier handling . Connector Types: Common connectors include LC to LC duplex, with options for UPC or APC polish, enabling low insertion loss (≤0.3 dB) and high return loss (≥50 dB) for reliable signal integrity . Environmental Resistance: Designed to withstand temperature extremes, moisture, UV exposure, and mechanical stress, making them ideal for FTTH networks, industrial sites, and outdoor telecom infrastructure .ApplicationsFTTH (Fiber to the Home) deployments for residential or commercial networks.Outdoor backbone networks connecting buildings or data centers.Industrial and harsh environments, including roads, snowfields, and construction sites.High-speed Ethernet networks requiring 1G, 10G, 40G, or 100G connectivity.SummaryA single-mode dual-core outdoor fiber optic cable combines high-speed transmission capability with mechanical robustness and environmental protection, making it suitable for long-distance outdoor installations. When selecting a cable, consider fiber type (OS2), armoring, jacket material, connector type, and installation method to ensure optimal performance and durability .
