The JBX42644 15-meter SC/APC to LC/UPC duplex singlemode fiber patch cable represents a premium solution for professional network infrastructure deployment. Specifically engineered to bridge SC/APC and LC/UPC connector types, this cable accommodates mixed environments where equipment utilizes different connector standards. Technical Excellence: Built with 9/125 singlemode fiber featuring G.657.A1 glass specifications, this cable delivers superior performance across telecommunications wavelengths. The measured attenuation of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensures minimal signal loss over extended runs. With insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB, the cable meets rigorous performance standards tested in accordance with ANSI/TIA/EIA-455-171-A-2001. Compliance & Safety: TAA compliance makes this cable suitable for government, educational, and institutional procurement requirements. The yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket ensures safe installation in building risers and plenum spaces. The cable incorporates RoHS/ELV compliance and EU directive 2002/95/EC certification, reflecting environmental responsibility. Practical Design: The 1.8mm outside diameter provides flexibility for cable management and installation in constrained spaces. The duplex configuration with Type A to B crossover polarity represents the most common cross-connect configuration in telecommunications environments. Custom lengths are available to match specific deployment requirements. Applications: Ideal for fiber-to-the-building (FTTB) installations, long-distance telecommunications links, data center interconnects, and any scenario requiring SC/APC to LC/UPC conversion. Compatible with various telecommunications and networking equipment utilizing these connector types. Warranty & Support: 90-day limited warranty provides confidence in product quality. Ships from multiple U.S. locations (Danville, CA; Fort Worth, TX; Beaufort, SC) with free standard shipping on orders exceeding $99.
