The JBX86178 85-meter SC/SC duplex singlemode fiber patch cable represents premium telecommunications-grade connectivity for organizations demanding reliable, long-distance fiber signal transmission. This professional-specification cable combines advanced optical engineering with compliance certifications required by government and enterprise buyers. **Technical Excellence:** Designed with 9/125 singlemode fiber core and G.657.A1 specification, this cable achieves exceptional optical performance. Insertion loss measures ≤0.35dB (0.15dB typical), while return loss exceeds ≥20dB—specifications validated through ANSI/TIA/EIA-455-171-A-2001 standards testing. Wavelength-specific attenuation of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensures consistent performance across multiple transmission bands. **Built for Enterprise Reliability:** The SC/UPC connectors feature Type A-to-B crossover polarity—industry standard for duplex patch cords. The 1.8mm outside diameter jacketing accommodates dense cable management scenarios while maintaining durability. Riser-rated OFNR jacketing provides critical fire safety compliance for in-building installations, essential for data centers and commercial infrastructure. **Compliance & Procurement:** TAA compliance satisfies federal procurement requirements, while RoHS and EU directive 2002/95/EC certification meets environmental regulations worldwide. This cable meets the stringent standards required by government agencies, defense contractors, and regulated industries. **Applications:** Perfect for backbone connections, inter-facility links, long-distance data transmission, telecommunications infrastructure, and enterprise network backhaul. The 85-meter length accommodates campus environments, multi-floor installations, and outdoor spans. **Flexibility & Support:** Custom lengths available for unique deployment scenarios. Backed by 90-day limited warranty. Ships from strategically located U.S. warehouses (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99.
