The JBX89207 80-meter SC/ST duplex singlemode fiber patch cable represents a professional-grade solution for organizations requiring reliable, long-distance fiber optic connectivity. This TAA-compliant cable is specifically engineered to meet federal procurement requirements, making it ideal for government contractors and agencies. **Technical Specifications:** Constructed with 9/125 singlemode fiber core and G.657.A1 glass fiber, this cable delivers exceptional performance characteristics. The duplex configuration provides two independent fiber strands in a single assembly, enabling full-duplex communication. At 1310nm, attenuation measures 0.25dB/km, while 1550nm wavelengths experience 0.35dB/km, ensuring consistent signal integrity across critical communication bands. **Performance Standards:** Tested in accordance with ANSI/TIA/EIA-455-171-A-2001, the cable demonstrates insertion loss of ≤0.35dB with a typical performance of 0.15dB. Return loss exceeds 20dB, meeting industry benchmarks for enterprise installations. The SC/UPC to ST/UPC connectors utilize Type A to B crossover polarity, the most common configuration for duplex patch cords, eliminating compatibility concerns. **Installation & Protection:** The purple OFNR (Optical Fiber Non-Conductive Riser) rated jacket provides flame resistance and compliance with building codes for vertical cable installations. The 1.8mm outer diameter allows for efficient cable management through tight conduit runs. Compact dimensions and flexible design facilitate deployment in confined spaces common to data centers and network closets. **Compliance & Warranty:** Fully RoHS and ELV compliant per EU directive 2002/95/EC, this cable meets environmental and procurement standards for international deployments. The 90-day limited warranty provides peace of mind for critical infrastructure investments. Custom lengths are available to accommodate specific installation requirements. **Shipping & Logistics:** Ships from three strategically located US facilities (Danville CA, Fort Worth TX, and Beaufort SC) ensuring rapid delivery. Free standard shipping applies to orders exceeding $99, with quantity discounts available for bulk deployments.
