The JBX88386 ST/ST Duplex Singlemode Fiber Patch Cable represents the ideal solution for enterprise-class network deployments, data centers, and telecommunications infrastructure requiring reliable single-mode fiber connectivity over 25-meter distances. **Key Features & Specifications:** This professional-grade patch cable combines exceptional optical performance with robust construction. The 9/125 singlemode core fiber delivers ultra-low attenuation at 0.25 dB/km (1310nm) or 0.35 dB/km (1550nm), ensuring minimal signal degradation across long-distance runs. With insertion loss rated at ≤0.35dB (typical 0.15dB) and return loss ≥20dB, this cable exceeds industry standards for high-fidelity data transmission. **Technical Advantages:** The G.657.A1 glass fiber specification provides superior bend radius characteristics while maintaining strict performance standards. The OFNR riser-rated jacketing ensures fire safety compliance for building installations, while the compact 1.8mm outside diameter facilitates cable management in tight spaces. ST/UPC connectors deliver superior optical characteristics compared to APC alternatives for most duplex applications. **Compliance & Quality Assurance:** Fully TAA-compliant and manufactured to rigorous ANSI/TIA/EIA standards, this cable meets government procurement requirements. RoHS and EU Directive 2002/95/EC compliant materials ensure environmental responsibility. All attenuation testing follows established telecommunications protocols. **Ideal Applications:** - Enterprise network backbone connections - Data center fiber optic infrastructure - Telecommunications equipment interconnection - High-speed LAN installations - Long-distance signal transmission **Available Benefits:** Custom lengths available for specific installation requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. 90-day limited warranty provides peace of mind investment protection. **Professional Installation Tip:** Ensure proper handling during installation to maintain optical performance. Avoid sharp bends exceeding the cable's minimum bend radius specifications.
