The JBX88290 8m ST/ST duplex singlemode fiber patch cable represents premium connectivity for professional fiber optic installations. Featuring industry-standard ST/UPC connectors on both ends, this cable delivers the performance reliability demanded by data centers, telecommunications facilities, and enterprise networks. **Technical Excellence:** Constructed with 9/125 singlemode core and G.657.A1 glass fiber, this cable minimizes signal loss over extended distances. The insertion loss of ≤0.35dB and return loss of ≥20dB exceed industry standards, ensuring optimal signal transmission. Attenuation testing confirms performance at both 1310nm (0.25 dB/km) and 1550nm (0.35 dB/km) wavelengths, supporting diverse optical applications. **Compliance & Safety:** TAA compliance makes this cable suitable for government and federal projects. RoHS/ELV certification ensures environmental responsibility, meeting EU directive 2002/95/EC. The riser-rated OFNR jacketing provides fire safety compliance for in-building use, while the 1.8mm outside diameter ensures compatibility with standard cable management systems. **Practical Features:** The duplex configuration with Type A to B crossover polarity accommodates standard network installations. Green jacketing aids in color-coded network organization. Custom length availability accommodates specialized installation requirements. The 90-day limited warranty provides customer peace of mind. **Applications:** Ideally suited for LAN/WAN backbone connections, data center patch panel interconnections, telecommunications networks, and high-speed data transmission requiring singlemode performance. The 8-meter length bridges equipment distances common in professional installations. **Shipping & Support:** Free standard shipping on orders exceeding $99. Ships from multiple US locations (Danville, CA; Fort Worth, TX; Beaufort, SC) ensuring rapid delivery. Manufactured in Taiwan, US, or China with consistent quality standards.
