The JBX88217 is a professional-grade 80-meter ST/ST duplex singlemode fiber patch cable engineered for telecommunications and data center professionals who demand reliability, performance, and compliance. This comprehensive solution addresses the critical need for extended optical runs in modern network infrastructure. **Key Performance Features:** The cable utilizes a 9/125 singlemode core with G.657.A1 glass fiber technology, enabling long-distance transmission with exceptional signal fidelity. Measured insertion loss of ≤0.35dB (typical 0.15dB) ensures minimal signal degradation, while return loss of ≥20dB guarantees stable connections. Performance is independently verified at both 1310nm and 1550nm wavelengths, accommodating diverse optical equipment and networking standards. **Robust Construction:** The 1.8mm outer diameter cable features OFNR riser-rated jacketing, suitable for in-building installations including plenum and riser spaces. The high-visibility yellow jacket simplifies cable identification and management in complex installations. Duplex configuration with Type A to B crossover polarity enables bidirectional communication on a single cable run, reducing installation complexity. **Compliance & Certification:** Full TAA compliance meets government procurement requirements, while RoHS/ELV directives ensure environmental responsibility. Manufacturing in Taiwan, the US, and China provides supply chain flexibility. Rigorous attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards guarantees consistent quality. **Applications:** Perfect for telecommunications facilities, data center interconnects, campus networks, and long-distance signal transmission where singlemode technology is required. The 80-meter length accommodates extensive horizontal and backbone runs. **Additional Benefits:** 90-day limited warranty provides peace of mind. Free standard shipping on orders exceeding $99. Custom length options available for specialized installations. Ships from multiple US locations for expedited delivery. Invest in optical infrastructure built for performance, compliance, and longevity.
