The JBX42374 SC/APC to ST/UPC duplex singlemode fiber patch cable represents a premium solution for optical network connectivity requiring precise signal transmission and reliable performance. Manufactured to exacting standards, this 15-meter cable bridges the gap between different connector types while maintaining superior signal integrity. **Technical Excellence** Construction utilizes 9/125 singlemode fiber with G.657.A1 glass composition, offering the optimal balance between transmission efficiency and bend radius tolerance. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm demonstrate exceptional low-loss performance across standard telecom wavelengths. The cable's insertion loss of ≤0.35dB with typical values around 0.15dB ensures minimal signal degradation over distance. **Robust Construction** The yellow PVC jacket provides immediate visual identification while the 1.8mm outer diameter accommodates dense patch panel arrangements without excessive bulk. OFNR (Optical Fiber Non-conductive Riser) rating ensures compliance with fire safety codes for vertical riser installations and plenum-adjacent applications. The durable plastic accessory housing protects delicate fiber strands from environmental stressors. **Regulatory Compliance & Standards** Full TAA compliance certifies this cable for government and institutional procurement. RoHS and EU directive 2002/95/EC compliance reflects commitment to eliminating hazardous substances. Attenuation testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality across manufacturing batches. **Ideal Applications** Perfect for data centers, telecommunications facilities, ISP infrastructure, and enterprise network installations where SC/APC and ST/UPC equipment requires interconnection. The Type A to B crossover configuration supports standard duplex patch cord applications without requiring additional adapters or retermination. **Flexibility & Support** Available in custom lengths for non-standard installations. Ships from multiple US locations (Danville, CA; Fort Worth, TX; Beaufort, SC) ensuring rapid delivery. Complimentary standard shipping applies to orders exceeding $99. 90-day limited warranty covers manufacturing defects.
