The JBX91188 6m SC/ST Duplex Singlemode Fiber Patch Cable represents a reliable solution for professional-grade optical network connections. With its 9/125 core specification, this cable delivers the precision needed for long-distance, high-bandwidth telecommunications applications. **Key Specifications:** This singlemode cable features a 9/125 core diameter with G.657.A1 glass fiber, ensuring minimal signal degradation. The SC/UPC to ST/UPC connector configuration with Type A to B crossover polarity makes it compatible with most duplex patch cord installations. At 1.8mm outside diameter, it integrates seamlessly into existing cable infrastructure. **Performance Metrics:** Insertion loss remains exceptionally low at ≤0.35dB (typical 0.15dB), while return loss exceeds ≥20dB. Attenuation performance is measured at both 1310 nm (0.25 dB/km) and 1550 nm (0.35 dB/km), ensuring consistent performance across multiple wavelength windows. **Quality & Compliance:** TAA-compliant construction meets government procurement requirements. RoHS and EU directive 2002/95/EC certification ensures environmental responsibility. Testing follows ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing industry-leading quality. **Practical Applications:** Ideal for data centers, telecommunications facilities, enterprise networks, and fiber-to-the-desk installations. The green OFNR riser-rated jacket provides fire safety compliance for in-wall installations. **Value Proposition:** Custom lengths available for specialized requirements. Free standard shipping on orders exceeding $99. 90-day limited warranty provides peace of mind. Ships from multiple U.S. locations for rapid delivery. **Care & Storage:** Store in cool, dry environments. Avoid excessive bending (minimum bend radius 30mm). Protect connectors with dust caps when not in use. Handle with care to maintain optical performance.
