The JBX88221 1-meter ST/ST duplex singlemode fiber patch cable represents a critical component for modern fiber optic networks demanding exceptional performance and reliability. Designed for professionals and organizations prioritizing network infrastructure quality, this cable delivers the precision connectivity required in demanding telecommunications and data center environments. **Superior Optical Performance** This singlemode fiber patch cable features a 9/125 core with G.657.A1 glass fiber specifications, engineered to minimize signal loss and maximize data transmission quality. With industry-leading insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, the cable ensures pristine signal integrity across long-distance communications. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm meet rigorous ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance. **Professional-Grade Construction** The ST/UPC connectors provide reliable, repeatable connections with minimal reflections. Type A to B crossover polarity configuration represents industry best practices for duplex patch cords, ensuring seamless integration with existing infrastructure. The red OFNR-rated (riser-rated) jacket exceeds fire safety requirements while maintaining a slim 1.8mm outside diameter for flexible routing through tight spaces. **Compliance & Reliability** Fully TAA-compliant and manufactured to meet EU directive 2002/95/EC (RoHS/ELV) standards, this cable suits government and enterprise procurement requirements. Available in custom lengths beyond the standard 1m configuration, it adapts to virtually any deployment scenario. The 90-day limited warranty reflects manufacturer confidence in product durability. **Applications** Ideal for server interconnects, data center uplinks, telecommunications infrastructure, campus networks, and any mission-critical fiber installations requiring singlemode performance. Shipped from strategically located US warehouses with free standard shipping on orders exceeding $99. **Why Choose This Cable** When network reliability directly impacts business operations, the JBX88221 delivers the optical performance, compliance certifications, and construction quality that professionals depend on.
