The JBX87197 30m SC/ST Duplex Singlemode Fiber Patch Cable represents a professional-grade solution for organizations requiring reliable, long-distance optical fiber connectivity. This cable is engineered to meet rigorous telecommunications standards and is ideal for critical infrastructure applications. **Technical Specifications:** This duplex singlemode patch cable features a 9/125 micrometer core with G.657.A1 glass fiber, providing optimal light transmission characteristics. The cable measures 30 meters in length with SC/UPC and ST/UPC connectors configured in Type A to B crossover polarity—the industry standard for duplex patch cords. The 1.8mm outer diameter allows for efficient cable management in tight spaces. **Performance Characteristics:** With insertion loss ratings of ≤0.35dB (0.15dB typical) and return loss specifications of ≥20dB, this cable ensures minimal signal degradation over extended distances. Attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards confirms performance at both 1310nm (0.25 dB/km) and 1550nm (0.35 dB/km) wavelengths, making it suitable for diverse telecommunications applications. **Compliance & Safety:** TAA compliant and RoHS/ELV certified, this cable meets stringent regulatory requirements for government and institutional procurement. The OFNR (Riser Rated) jacketing ensures safe installation in building plenums and vertical runs. **Applications:** Ideal for data centers, telecommunications facilities, campus networks, and any environment requiring secure, high-performance fiber connectivity. The SC/ST connector combination provides compatibility with legacy and modern network equipment. **Warranty & Support:** Backed by a 90-day limited warranty. Custom lengths available upon request. Free standard shipping on orders exceeding $99, with shipment from conveniently located US warehouses in California, Texas, and South Carolina.
