The JBX88229 7m ST/ST Duplex Singlemode Fiber Patch Cable represents a professional-grade solution for mission-critical fiber optic network installations. This cable combines precision engineering with stringent quality standards to ensure reliable signal transmission in demanding environments. **Superior Technical Specifications:** With a 9/125 micron core and G.657.A1 glass fiber construction, this singlemode cable excels in long-distance, high-bandwidth applications. The measured insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB exceed industry standards, minimizing signal degradation. Attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm meet rigorous ANSI/TIA/EIA-455-171-A specifications. **Robust Construction:** The 1.8mm outside diameter duplex cable features Type A to B crossover polarity—the industry standard for duplex patch cords. OFNR riser-rated jacketing ensures flame resistance and compliance with building safety codes, making it suitable for in-building distribution systems. **Government and Enterprise Ready:** TAA compliance and RoHS/ELV certification make this cable ideal for government procurement, federal projects, and organizations requiring verified components. The ST/UPC to ST/UPC connectors provide cost-effective connectivity without the premium pricing of LC or MTP alternatives. **Versatile Applications:** Designed for data centers, telecommunications infrastructure, campus networks, and audiovisual installations, this cable handles demanding environments from server rooms to network closets. Available in custom lengths for specific deployment requirements. **Value and Support:** With free standard shipping on orders over $99 and warehousing in California, Texas, and South Carolina, fast delivery is guaranteed. The 90-day limited warranty provides peace of mind on your network investment.
