The JBX88326 ST/ST Duplex Singlemode Fiber Patch Cable represents a critical component for high-performance telecommunications infrastructure. This 25-meter cable assembly combines precision engineering with compliance certifications required by government and enterprise buyers. **Technical Specifications:** This duplex patch cable features dual 9/125 micron singlemode fiber strands with G.657.A1 glass composition, optimized for both 1310nm and 1550nm wavelengths. Attenuation performance meets ANSI/TIA/EIA-455-171-A specifications at 0.25dB/km (1310nm) and 0.35dB/km (1550nm). The insertion loss specification of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB ensures minimal signal degradation over the 25-meter span. **Compliance & Certification:** TAA (Trade Agreements Act) compliance makes this cable eligible for federal government contracts and GSA schedule purchases. RoHS and ELV directives compliance ensures environmental responsibility and reduced hazardous substances. The 90-day limited warranty provides confidence in quality and reliability. **Design Features:** ST/UPC connectors with Type A to B crossover polarity deliver straightforward plug-and-play installation. The OFNR (Optical Fiber Nonconductive Riser) rated jacket meets fire and safety standards for vertical cable runs in building installations. Compact 1.8mm outer diameter enables flexible routing without compromising durability. **Applications:** Ideal for data centers, telecommunications closets, network backbone connections, and laboratory test environments. The singlemode configuration supports long-distance transmission critical for campus networks and carrier-class installations. Custom lengths available for specific deployment requirements. **Value Proposition:** Shipping from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensures rapid delivery. Free standard shipping on orders exceeding $99 reduces total cost of ownership. Manufactured with quality oversight across Taiwan, US, and China facilities.
