The JBX85186 2-meter SC/ST duplex singlemode fiber patch cable represents a premium solution for professional fiber optic networking applications. Engineered with precision-aligned SC/UPC and ST/UPC connectors, this cable delivers reliable signal transmission in both campus networks and long-haul telecommunications infrastructure. Technical Excellence: Built with G.657.A1 singlemode glass fiber featuring a 9/125 micrometer core diameter, this cable supports attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm wavelengths. Insertion loss measurements, tested per ANSI/TIA/EIA-455-171-A standards, average just 0.15dB with a maximum of 0.35dB, ensuring minimal signal loss over the 2-meter length. Return loss specifications of ≥20dB prevent problematic back-reflections that could degrade system performance. Compliance & Standards: TAA compliance makes this cable eligible for government procurement, while RoHS/ELV certification demonstrates environmental responsibility. The 1.8mm outside diameter with OFNR riser-rated jacketing provides safe installation in building cable trays and conduit systems. Duplex Configuration: The Type A to B crossover polarity configuration represents the industry standard for duplex patch cords, enabling simultaneous bidirectional communication without additional equipment. The distinctive yellow jacket facilitates quick visual identification in dense cable management environments. Versatility & Value: Available in custom lengths beyond the standard 2-meter offering, this cable adapts to unique network layouts. Free standard shipping on orders exceeding $99 provides cost-effective procurement. Ships from multiple U.S. locations (California, Texas, South Carolina) ensuring rapid delivery. The 90-day limited warranty provides peace of mind for critical network installations. Ideal Applications: Data centers, telecommunications hubs, university networks, hospital systems, financial institutions, and any environment requiring reliable, standards-compliant singlemode fiber connectivity.
