The JBX42641 SC/APC to LC/UPC duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network infrastructure. This 9-meter cable is engineered to deliver exceptional optical performance across demanding telecommunications applications. Technical Excellence: Built with a 9/125 singlemode core conforming to G.657.A1 standards, this cable provides superior performance characteristics. The SC/APC connectors feature angled physical contact geometry that minimizes back-reflection, while LC/UPC connectors offer perpendicular contact surfaces. This Type A to B crossover configuration represents the industry standard for duplex patch cords, enabling seamless integration into existing network architectures. Performance Specifications: Attenuation is rigorously tested to ≤0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm, with typical insertion loss of just 0.15dB—ensuring minimal signal degradation. Return loss exceeds 20dB, providing excellent signal integrity. The 1.8mm diameter jacketing combined with OFNR riser-rating provides durability while meeting commercial building fire codes. Compliance & Quality: TAA certification ensures procurement compatibility with government contracts and regulated industries. RoHS/ELV directive compliance demonstrates environmental responsibility. All products come with a 90-day limited warranty and are tested in accordance with ANSI/TIA/EIA-455-171-A standards. Practical Advantages: The distinctive yellow jacket simplifies cable management and identification in dense fiber installations. The 9-meter length accommodates various installation scenarios from equipment racks to distributed fiber runs. Custom lengths are available for specialized requirements. Applications: Ideal for data centers, telecommunications networks, broadband installations, research facilities, and any environment requiring reliable singlemode fiber connectivity. The combination of SC/APC and LC/UPC connectors makes this cable valuable for legacy system integration and hybrid network environments. Shipping & Support: Free standard shipping on orders exceeding $99, with distribution from multiple U.S. locations ensuring rapid delivery.
