The JBX92186 SC/ST duplex singlemode fiber patch cable represents the gold standard for optical connectivity in professional networking environments. Manufactured to exacting standards with compliance to RoHS/ELV directives and TAA regulations, this cable meets the stringent requirements of government and enterprise procurement specifications. Technical Excellence: This 4-meter patch cable features a 9/125 singlemode fiber core with G.657.A1 glass fiber composition, specifically engineered for long-distance, high-bandwidth telecommunications. The duplex configuration provides two independent fiber strands in a single cable assembly, enabling simultaneous transmit and receive operations without signal interference. Attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensure minimal signal loss across industry-standard wavelengths, while the ≤0.35dB insertion loss and ≥20dB return loss measurements guarantee optimal signal integrity. Connector Specifications: The SC/UPC to ST/UPC connectors utilize Type A to B crossover polarity configuration, the most common standard for duplex patch cords. Both connector types are universal industry standards, ensuring broad compatibility with existing telecommunications infrastructure and networking equipment. Construction & Durability: The cable features riser-rated (OFNR) jacketing with a 1.8mm outside diameter, balancing durability with space efficiency in cable management systems. The white plastic accessory housing provides visual identification and fits standard telecommunications cabinets and conduits. Packaged with protective spacing, the cable arrives ready for immediate installation without requiring field termination. Applications: Perfect for data centers, telecommunications rooms, enterprise LANs, and any environment requiring reliable, TAA-compliant optical connectivity. The G.657.A1 fiber specification enables installation in tight bend radius applications when necessary, providing flexibility for complex network topologies. Compliance & Support: This cable is fully compliant with EU directive 2002/95/EC (RoHS), making it suitable for government contracts and regulated procurement environments. Backed by a comprehensive 90-day limited warranty and available in custom lengths for specialized installations. Free standard shipping on orders over $99, with shipment from multiple US locations ensuring rapid delivery.
