The JBX88381 9-meter ST/ST duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network infrastructure. Featuring dual strands with 9/125 singlemode cores and ST/UPC connectors in Type A to B crossover configuration, this cable delivers exceptional performance for high-speed data transmission. **Performance Specifications:** The cable achieves exceptional optical performance with insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB. Attenuation testing confirms compliance with ANSI/TIA/EIA-455-171-A-2001 standards at both 1310nm (0.25 dB/km) and 1550nm (0.35 dB/km) wavelengths, making it suitable for diverse fiber optic applications. **Compliance & Standards:** TAA compliant and RoHS/ELV certified (EU Directive 2002/95/EC), this cable meets stringent government and enterprise procurement requirements. The G.657.A1 fiber specification ensures superior bend radius performance without compromising signal quality. **Installation Features:** The distinctive purple OFNR (Riser Rated) jacket provides easy identification while accommodating diverse installation environments. With a compact 1.8mm outside diameter and 5.0mm width dimensions, it integrates seamlessly into cable management systems. The duplex configuration with Type A to B crossover polarity represents the most common standard for patch cord applications. **Applications & Use Cases:** Ideal for data centers, telecommunications hubs, enterprise networks, and fiber-to-the-desk deployments. The 9-meter length accommodates medium-distance backbone runs and interconnection requirements. Custom lengths are available for specialized installations. **Warranty & Support:** Protected by a 90-day limited warranty with free standard shipping on orders exceeding $99. Multiple U.S. warehouse locations (Danville CA, Fort Worth TX, Beaufort SC) ensure rapid delivery.
