The JBX91189 7-meter SC/ST Duplex Singlemode Fiber Patch Cable represents a professional solution for fiber optic network infrastructure. This cable is specifically designed to meet the demanding requirements of telecommunications, data center, and enterprise networking environments. Technical Excellence: Built with a 9/125 singlemode fiber core and G.657.A1 glass composition, this cable delivers exceptional optical performance. The insertion loss specification of ≤0.35dB (typical 0.15dB) ensures minimal signal degradation, while the ≥20dB return loss prevents reflective interference. These measured values comply with ANSI/TIA/EIA-455-171-A-2001 standards and provide reliable operation across both 1310nm and 1550nm wavelengths. Connector Configuration: The SC/UPC to ST/UPC connector pairing with Type A to B crossover polarity represents the industry-standard duplex patch cord configuration. This universal compatibility ensures seamless integration with existing network infrastructure and reduces installation complexity. Built for Compliance: The OFNR (Optical Fiber Non-conductive Riser) rated green jacket provides fire protection suitable for building risers and commercial installations. TAA (Trade Agreements Act) compliance certification makes this cable eligible for government and federal procurement programs. RoHS/ELV directive compliance ensures environmental responsibility without compromising performance. Practical Advantages: The compact 1.8mm outside diameter simplifies cable management in crowded patch panel environments. The 7-meter length provides flexibility for standard rack-to-rack and equipment-to-distribution distances. The distinctive green jacket aids in cable identification and organization. Custom length availability accommodates specialized installations. Reliability & Support: Backed by a 90-day limited warranty and manufactured in compliance with international standards, this patch cable provides dependable performance. Bulk packaging (10x10x10) supports both individual purchases and network-wide deployments. Free standard shipping on orders over $99 reduces total cost of ownership. Ideal for enterprises, data centers, telecommunications facilities, and network professionals requiring proven, standards-compliant fiber connectivity solutions.
