The JBX43686 LC/UPC to FC/APC 75-meter simplex singlemode fiber patch cable represents professional-grade connectivity for modern fiber optic networks. This single-strand cable configuration provides dedicated one-way signal transmission, making it ideal for applications requiring simplex communication pathways. **Technical Excellence:** Built with a 9/125 micron singlemode core and G.657.A1 glass fiber, this cable delivers superior performance characteristics. Tested insertion loss measures ≤0.35dB typical (maximum 0.35dB), while return loss exceeds 20dB specification. Attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensure minimal signal degradation across extended distances. All performance metrics comply with ANSI/TIA/EIA-455-171-A-2001 standards. **Regulatory Compliance & Safety:** Fully TAA compliant for government procurement contracts. RoHS/ELV directive certified (EU 2002/95/EC) ensures environmental responsibility. The OFNR (Optical Fiber Non-conductive Riser-Rated) jacket provides critical flame resistance, making this cable suitable for installation in vertical runs, plenums, and building pathways where fire safety standards apply. **Physical Specifications:** Compact 1.8mm outside diameter allows flexible routing and space-efficient cable management. The vibrant yellow jacket aids visual identification in installations and simplifies troubleshooting. Straight-through polarity configuration ensures straightforward connectivity between LC/UPC and FC/APC terminations. **Practical Applications:** Perfect for telecommunications networks, data center interconnects, telecommunications closets, and enterprise backbone installations. The 75-meter length accommodates longer building runs and remote equipment connections. Custom lengths available for specialized projects. **Warranty & Support:** Backed by a comprehensive 90-day limited warranty. Shipped from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99, ensuring quick delivery and cost-effective procurement. **Care & Maintenance:** Protect connectors with dust caps when not in use. Avoid bending beyond 35mm radius. Keep cable away from sharp objects and excessive heat. Regular inspection ensures optimal performance.
