The JBX88251 ST/ST Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity designed for mission-critical network applications. This 1-meter cable combines precision engineering with proven reliability for telecommunications, data centers, and enterprise networking environments. **Technical Excellence:** Constructed with 9/125 singlemode fiber and G.657.A1 glass specifications, this duplex cable delivers exceptional performance characteristics. The low insertion loss of ≤0.35dB (typical 0.15dB) and high return loss of ≥20dB ensure minimal signal degradation across attenuation testing at both 1310nm and 1550nm wavelengths. Attenuation specifications of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm exceed industry standards for singlemode transmission. **Installation and Compatibility:** Featuring ST/UPC to ST/UPC connectors in Type A to B crossover configuration, this cable integrates seamlessly with existing duplex installations. The 1.8mm outside diameter provides flexibility in tight conduit runs and equipment racks. OFNR riser rating allows safe use in plenum spaces and vertical installations, meeting building codes and fire safety requirements. **Compliance and Standards:** Fully TAA compliant and RoHS/ELV certified, this cable meets federal procurement requirements and environmental regulations. Testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent performance and reliability. Blue jacketing aids in cable management and network documentation. **Practical Benefits:** Available in custom lengths for specialized applications beyond the standard 1-meter configuration. The 90-day limited warranty provides confidence in product quality. Multiple U.S. shipping locations (Danville, CA; Fort Worth, TX; Beaufort, SC) enable rapid delivery with free standard shipping on orders exceeding $99. **Ideal Applications:** Perfect for data center patch panel connections, telecommunications infrastructure, long-haul fiber networks, enterprise backbone installations, and high-performance computing environments where signal integrity is critical. Whether upgrading existing infrastructure or building new installations, the JBX88251 delivers the performance, reliability, and compliance required for professional network deployments.
