The JBX88316 ST/ST Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity for mission-critical network applications. This 4-meter cable is specifically engineered to meet the demanding requirements of telecommunications infrastructure, data center environments, and enterprise networks where reliability and performance are non-negotiable. Technical Excellence: Built with 9/125 singlemode fiber and G.657.A1 glass construction, this cable is optimized for long-distance, high-bandwidth signal transmission. The exceptional insertion loss specification of ≤0.35dB (typical 0.15dB) at both 1310nm and 1550nm wavelengths ensures minimal signal degradation. Return loss exceeding 20dB provides superior signal integrity, critical for sensitive optical communications. Connector Performance: The ST/UPC connectors feature polarity Type A to B crossover configuration—the industry standard for duplex patch cords. This design facilitates seamless integration with existing ST-based infrastructure while maintaining optimal signal coupling. Compliance & Durability: TAA compliant manufacturing ensures government procurement compatibility. OFNR (Optical Fiber Non-Conductive Riser) jacketing provides flame-retardant protection, making it suitable for building plenum installations. The cable meets rigorous ANSI/TIA/EIA-455-171-A-2001 standards for attenuation testing. Flexibility & Customization: While this product ships in a standard 4-meter length, custom length configurations are available to accommodate unique installation requirements. The 1.8mm outer diameter provides optimal balance between flexibility and durability. Value Proposition: Backed by a 90-day limited warranty and qualifying for free standard shipping on orders over $99, this cable delivers enterprise-quality performance at competitive pricing. Ships from multiple US locations for rapid delivery. Ideal Applications: Data center interconnects, telecommunications equipment connections, fiber optic network upgrades, laboratory testing setups, and any installation requiring reliable singlemode fiber connectivity.
