The JBX88319 7-meter ST/ST duplex singlemode fiber patch cable represents a premium solution for telecommunications and network infrastructure professionals who demand reliability and compliance. This comprehensive guide covers everything you need to know about this essential networking component. TECHNICAL SPECIFICATIONS At its core, this cable features 9/125 singlemode fiber construction, optimized for long-distance signal transmission at 1310nm and 1550nm wavelengths. The attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure minimal signal loss over extended distances. With insertion loss of ≤0.35dB (typical 0.15dB) and return loss exceeding 20dB, this cable meets stringent performance requirements for enterprise-grade installations. KEY FEATURES & BENEFITS TAA compliance makes this cable ideal for government contracts, federal projects, and enterprise deployments requiring domestic manufacturing compliance. The G.657.A1 glass fiber provides superior bend radius characteristics for modern installation requirements. OFNR riser rating allows installation in building plenums without conduit, reducing installation costs and complexity. The ST/UPC to ST/UPC connectors with Type A to B crossover polarity ensure proper duplex communication in standard network architectures. APPLICATIONS Perfect for backbone connectivity, server-to-switch connections, building-to-building links, and telecommunications infrastructure. The 7-meter length accommodates typical data center and network closet layouts. Includes free standard shipping on orders over $99.
