The JBX85151 2m SC/SC Duplex Singlemode Fiber Patch Cable represents an essential connectivity solution for modern network infrastructure. Designed specifically for singlemode applications, this cable accommodates the demanding requirements of long-distance, high-bandwidth telecommunications and data center environments. **Technical Excellence:** Built with 9/125 micron singlemode fiber core and G.657.A1 glass fiber specification, this patch cable delivers superior performance characteristics. Tested to ANSI/TIA/EIA-455-171-A-2001 standards, it achieves insertion loss of just 0.15dB typical (maximum 0.35dB) and return loss exceeding 20dB. At 1310nm wavelength, attenuation measures 0.25dB/km, while 1550nm operation delivers 0.35dB/km attenuation—ideal for diverse optical network requirements. **Design & Construction:** The distinctive yellow OFNR-rated jacket (1.8mm outer diameter) ensures riser-rated fire safety compliance while facilitating quick cable identification in complex installations. Duplex configuration with SC/UPC connectors supports Type A to B crossover polarity, the industry standard for patch cord applications. This straightforward compatibility eliminates confusion during installation and maintenance. **Practical Benefits:** Available in custom lengths beyond the standard 2m offering, this cable adapts to various network geometries and rack configurations. RoHS/ELV compliant construction meets environmental and regulatory requirements. The 90-day limited warranty provides purchase confidence, while free standard shipping on orders exceeding $99 delivers value-conscious buying. Ships from strategically located US warehouses (Danville CA, Fort Worth TX, Beaufort SC) for expedited delivery. **Ideal Applications:** Network operators, systems integrators, and IT professionals utilize this cable for enterprise backbone connections, campus networking, and telecommunications infrastructure. The combination of proven singlemode technology, rigorous quality testing, and accessible pricing makes it suitable for both planned upgrades and emergency replacements in mission-critical environments.
