The JBX43141 50-meter SC/APC to SC/UPC simplex singlemode fiber patch cable represents the pinnacle of fiber connectivity solutions for professional network environments. Designed to meet the rigorous demands of modern telecommunications infrastructure, this cable combines precision engineering with cost-effective performance. **Technical Specifications:** Features a 9/125 singlemode core with G.657.A1 glass fiber composition, delivering superior bend radius performance compared to standard G.652.D fiber. With an exceptionally low typical insertion loss of 0.15dB and maximum of 0.35dB, this cable minimizes signal attenuation across critical wavelengths (1310nm and 1550nm). The return loss specification of ≥20dB ensures minimal signal reflection, critical for maintaining signal integrity in long-distance transmissions. **Design & Build Quality:** The bright yellow 1.8mm diameter jacket provides excellent visibility for rapid identification and cable management in complex installations. Riser-rated (OFNR) jacketing ensures compliance with building fire codes, making it suitable for vertical runs in multi-story installations. The 1.8mm outside diameter facilitates easy routing through existing cable trays and conduits without requiring extensive modifications. **Compliance & Standards:** TAA (Trade Agreements Act) compliant, this cable meets all federal procurement requirements. RoHS/ELV directive compliance ensures environmentally responsible manufacturing. Attenuation testing conducted in accordance with ANSI/TIA/EIA-455-171-A-2001 industry standards guarantees consistent, reliable performance. **Practical Applications:** Ideal for data center interconnects, telecommunications infrastructure, FTTD (Fiber-to-the-Desk) deployments, network backbone connections, and laboratory testing environments. The simplex configuration makes it perfect for unidirectional signal transmission where separate cables are required for full-duplex communication. **Flexibility & Support:** Available in custom lengths beyond the standard 50-meter configuration to accommodate unique installation requirements. Free standard shipping on orders over $99, with inventory maintained at multiple U.S. distribution centers (California, Texas, and South Carolina) for rapid delivery. Comprehensive 90-day limited warranty provides peace of mind on your infrastructure investment.
