The JBX42376 SC/APC to ST/UPC duplex singlemode fiber patch cable represents professional-grade connectivity engineered for mission-critical network infrastructure. This 25-meter cable combines precision fiber optics with reliable connector technology to deliver consistent performance in telecommunications, data centers, and enterprise networks. Technical Excellence: Built with 9/125 singlemode fiber and G.657.A1 glass specifications, this cable achieves attenuation of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm. The Type A to B crossover polarity configuration is ideal for duplex patch cord applications. Insertion loss measures ≤0.35dB with typical performance of just 0.15dB, while return loss exceeds 20dB, ensuring minimal signal reflection and maximum data integrity. Quality Assurance & Compliance: Each cable undergoes rigorous attenuation testing in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. TAA compliance and RoHS/ELV certification ensure this cable meets federal procurement requirements and environmental regulations worldwide. The robust 1.8mm outside diameter plastic jacketing with OFNR rating provides superior flame resistance and durability for building backbone installations. Key Features: • Yellow OFNR jacket for easy identification and fire safety • Duplex configuration with dual fiber strands • Low insertion loss (0.15dB typical) for extended transmission distances • Custom length availability for flexible deployment • Ships from multiple US locations for rapid delivery • 90-day limited warranty Ideal Applications: This cable excels in single-mode fiber networks, telecommunications infrastructure, data center interconnects, and campus backbone installations. The SC/APC to ST/UPC connector combination accommodates mixed-connector environments, making it valuable for network upgrades and hybrid deployments. Customer Benefits: Free standard shipping on orders over $99, custom length availability, and multi-location domestic inventory ensure rapid delivery. The yellow jacket simplifies cable management and network troubleshooting, while TAA compliance opens access to government and institutional purchasing programs.
