The JBX90178 85-meter SC/SC duplex singlemode fiber patch cable represents professional-grade connectivity infrastructure designed for mission-critical telecommunications, data center, and enterprise network applications. This comprehensive solution addresses the need for extended-length fiber runs while maintaining superior optical performance and regulatory compliance. Technical Excellence: Constructed with genuine 9/125 singlemode fiber core using G.657.A1 specification glass fiber, this cable delivers industry-leading performance metrics. The insertion loss specification of ≤0.35dB (typical 0.15dB) ensures minimal signal degradation, while return loss of ≥20dB prevents signal reflections that compromise network quality. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm conform to ANSI/TIA/EIA standards, making it suitable for both traditional and dense wavelength division multiplexing (DWDM) applications. Advanced Connectivity: The SC/UPC connector configuration provides low back-reflection characteristics essential for single-mode applications. Type A to B crossover polarity represents the industry standard for duplex patch cords, ensuring compatibility with existing infrastructure. The robust 1.8mm outer diameter jacket with OFNR riser rating allows installation in building spaces while maintaining fire safety requirements. Compliance and Reliability: TAA (Trade Agreements Act) compliance enables use in government procurement and secure facility deployments. RoHS and ELV directive compliance demonstrates environmental responsibility and global regulatory adherence. Manufacturing across US, Taiwan, and China facilities ensures consistent quality and supply chain reliability. Practical Advantages: The distinctive pink color facilitates cable management and identification in complex installations. The 85-meter length minimizes splice points and connection complexity compared to multiple shorter cables. Custom length availability accommodates unique infrastructure requirements. Free standard shipping on qualifying orders and 90-day limited warranty demonstrate manufacturer confidence in product durability. Ideal Applications: Telecommunications networks, data center interconnects, long-distance campus connectivity, carrier-grade backbone networks, DWDM systems, and enterprise network infrastructure requiring extended reach with minimal signal loss.
