The JBX91004 2.5-meter LC/LC duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network environments. Built with precision 9/125 singlemode fiber core, this cable maintains superior optical performance across standard telecommunications wavelengths. Technical Excellence: This duplex patch cable features dual LC/UPC connectors in a Type A to B crossover polarity configuration—the industry standard for duplex patch cords. The singlemode fiber construction enables long-distance transmission with minimal signal degradation. Measured attenuation of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensures optimal performance for both legacy and next-generation network equipment. Compliance & Certification: Full TAA (Trade Agreements Act) compliance makes this cable suitable for U.S. government and federal agency procurement. RoHS and ELV directive compliance ensures environmental responsibility. Riser-rated OFNR jacketing provides critical fire safety for in-building backbone applications, while the distinctive green jacket aids in visual cable identification and network management. Design & Durability: The compact 1.8mm outside diameter allows for high-density cable management in crowded patch panels and server racks. Premium plastic accessories and construction deliver reliability in demanding environments. The cable meets rigorous testing standards established by ANSI/TIA/EIA-455-171-A-2001. Flexibility & Value: Custom length options allow configuration to exact specifications, eliminating waste and installation complexity. Multiple fulfillment locations (Danville CA, Fort Worth TX, Beaufort SC) enable rapid delivery. Free standard shipping on orders exceeding $99 reduces total cost of ownership. Applications: Perfect for data center interconnects, telecommunications cabinet backbone connections, medical imaging networks, and any enterprise application requiring duplex singlemode fiber transmission. The Type A to B crossover configuration is ready for immediate deployment without additional adapters. 90-day limited warranty provides peace of mind for critical infrastructure investments.
