The JBX89058 85m LC/SC Duplex 9/125 Singlemode Fiber Patch Cable represents a premium solution for professional fiber optic network installations. Manufactured to exacting standards, this purple-jacketed cable combines superior optical performance with stringent compliance requirements. **Technical Excellence** Features 9/125 core singlemode fiber with G.657.A1 glass composition, specifically designed for single-mode light transmission. The cable achieves exceptional attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, ensuring minimal signal loss over extended runs. Insertion loss measures ≤0.35dB (0.15dB typical) with return loss ≥20dB, exceeding industry standards for telecommunications applications. **Connector Configuration** LC/UPC to SC/UPC connectors with Type A to B crossover configuration enable reliable connections in duplex applications. This standard polarity setup simplifies installation and reduces compatibility issues in mixed equipment environments. **Compliance & Certification** TAA compliant for government procurement and RoHS certified per EU directive 2002/95/EC. Testing conducted per ANSI/TIA/EIA-455-171-A-2001 standards ensures documented performance specifications. The riser-rated OFNR jacketing (1.8mm OD) meets commercial building fire codes and safety requirements. **Applications** Ideal for telecommunications infrastructure, data center interconnects, campus network backbone installations, and carrier-grade optical networks. The 85-meter length accommodates mid-range building and facility routing requirements. **Reliability & Support** Backed by 90-day limited warranty. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Custom lengths available for specialized project requirements. **Maintenance** Store cables in dry, temperature-controlled environments. Avoid bending radius below 15cm to prevent fiber microbending losses. Clean connectors before mating using lint-free materials and approved fiber optic cleaning solutions.
