The JBX85179 85-meter SC/SC duplex singlemode fiber patch cable represents a premium solution for telecommunications professionals, data center operators, and network integrators requiring reliable long-distance fiber connectivity. Manufactured to exacting standards with G.657.A1 grade glass fiber, this cable delivers superior optical performance critical for modern high-speed networks. **Technical Excellence** This singlemode fiber patch cable features a precision 9/125 micron core optimized for single-mode transmission. The cable achieves exceptional attenuation specifications: 0.25dB/km at 1310nm and 0.35dB/km at 1550nm, with typical insertion loss of just 0.15dB. Return loss exceeds 20dB, ensuring signal integrity across extended 85-meter runs. These performance metrics exceed industry standards and undergo rigorous testing per ANSI/TIA/EIA-455-171-A-2001. **Connectivity & Compliance** Equipped with SC/UPC connectors in the most common Type A to B crossover configuration, this duplex cable simplifies installation and reduces configuration errors. TAA compliance ensures approval for government and institutional procurement, while RoHS/ELV directive certification demonstrates environmental responsibility. The OFNR riser-rated jacket meets safety codes for building installations. **Practical Advantages** The distinctive yellow 1.8mm jacket provides excellent visibility in crowded cable trays and conduits, facilitating identification during troubleshooting and maintenance. The 85-meter length eliminates the need for multiple shorter cables in many enterprise deployments, reducing connection points and potential signal loss. Free standard shipping on orders exceeding $99 combined with a 90-day limited warranty provides exceptional value and risk mitigation. **Application Scenarios** Ideal for backbone connections between network equipment, inter-rack fiber runs in data centers, campus network distribution, and long-distance telecommunications links. Compatible with any equipment featuring SC/UPC connectors, from managed switches to optical transceivers. **Customization Available** Custom length options accommodate specific deployment requirements beyond the standard 85-meter specification. Ships from multiple US locations (California, Texas, South Carolina) ensuring rapid delivery nationwide.
