The JBX90189 SC/ST Duplex Singlemode Fiber Patch Cable represents enterprise-grade connectivity designed for demanding network applications. This 7-meter cable combines precision engineering with practical functionality, making it an essential component for telecommunications infrastructure, data center installations, and high-performance network environments. Technical Excellence: Built with 9/125 singlemode fiber featuring G.657.A1 glass composition, this cable delivers superior optical performance. The SC/UPC to ST/UPC connector configuration provides Type A to B crossover polarity—the industry standard for duplex patch cords. With measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB, this cable ensures minimal signal degradation and optimal data transmission. Tested to ANSI/TIA/EIA-455-171-A standards, it supports both 1310 nm and 1550 nm wavelengths. Premium Construction: The 1.8mm outer diameter housing features OFNR (Optical Fiber Non-conductive Riser) rated pink jacketing, providing flame resistance and easy identification in crowded patch panels. The duplex configuration with two fiber strands enables simultaneous bidirectional communication, reducing cable runs and simplifying network architecture. Compliance & Reliability: TAA (Trade Agreements Act) compliant and RoHS/ELV directive certified, this cable meets government procurement standards and environmental regulations. Backed by a 90-day limited warranty, it ships from multiple US locations with free standard shipping on orders exceeding $99. Applications: Ideal for telecommunications networks, data center environments, ISP backbone connections, and enterprise LAN installations. The pink color facilitates quick identification and organization within complex network systems. Custom Solutions: Available in custom lengths to match your specific installation requirements, providing flexibility for unique network topologies. Whether upgrading existing infrastructure or building new connections, the JBX90189 delivers reliable, standards-compliant optical connectivity.
