The JBX91187 SC/ST Duplex Singlemode Fiber Patch Cable represents the gold standard in optical connectivity solutions for enterprise and government networks. This 5-meter cable combines superior optical performance with robust construction to ensure reliable data transmission in demanding environments. **Key Technical Features:** Built with 9/125 singlemode fiber and G.657.A1 specification, this duplex cable minimizes signal attenuation at standard telecommunications wavelengths (1310nm: 0.25dB/km, 1550nm: 0.35dB/km). The exceptionally low insertion loss of ≤0.35dB and return loss ≥20dB meet ANSI/TIA/EIA-455-171-A standards, ensuring optimal signal integrity for long-distance transmissions. **Construction & Compliance:** The 1.8mm outside diameter cable features an OFNR riser-rated green PVC jacket, providing flame resistance and durability for vertical installations. TAA compliance and RoHS/ELV certification make this cable ideal for government contracts and environmentally conscious organizations. All testing performed to industry standards guarantees consistent performance. **Application Versatility:** Perfect for telecommunications networks, data centers, fiber-to-the-premises (FTTP) installations, and emergency communication systems. The Type A to B crossover duplex configuration enables straightforward point-to-point connections without additional adapters. **Value Proposition:** Available in custom lengths to suit specific installation requirements, this cable ships from multiple US locations (California, Texas, South Carolina) for rapid delivery. Qualified orders receive free standard shipping on purchases over $99. The 90-day limited warranty provides peace of mind for critical infrastructure investments. **Why Choose This Cable:** When network performance matters, this professionally engineered patch cable delivers measurable optical excellence. Whether upgrading existing networks or building new infrastructure, the JBX91187 offers the reliability, compliance, and performance standards demanded by modern telecommunications environments.
