The JBX42687 represents professional-grade fiber optic connectivity engineered for the most demanding telecommunications, data center, and network infrastructure applications. This 80-meter FC/APC to LC/UPC duplex singlemode fiber patch cable combines precision engineering with proven reliability for mission-critical signal transmission. **Technical Excellence:** Built with 9/125 singlemode fiber core and G.657.A1 glass fiber specifications, this cable delivers superior performance characteristics. The measured insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation even over the 80-meter span. Attenuation testing at both 1310nm (0.25dB/km) and 1550nm (0.35dB/km) wavelengths confirms compliance with ANSI/TIA/EIA-455-171-A standards. **Versatile Connector Configuration:** The FC/APC to LC/UPC connector arrangement with Type A to B crossover polarity enables seamless integration into hybrid network environments where different connector types must be accommodated. This flexibility makes it an excellent solution for network upgrades and expansions. **Installation and Compliance:** Featuring a yellow OFNR (Optical Fiber Non-Conductive Riser) rated jacket with 1.8mm outside diameter, this cable meets building code requirements for riser installations. Full TAA compliance ensures qualification for government and institutional procurement processes. The cable is tested and certified to perform reliably in professional environments. **Practical Applications:** - Long-distance telecom networks - Data center interconnections - Building backbone cabling - Network upgrades and expansions - Hybrid connector environments - Government and institutional networks **Custom Solutions:** While the standard 80-meter length addresses most long-distance requirements, custom lengths are available to meet specific installation needs. This flexibility ensures you get exactly the right cable for your application. **Shipping and Support:** Shipped from multiple U.S. locations (California, Texas, South Carolina) for rapid delivery. Includes 90-day limited warranty and qualifies for free standard shipping on orders over $99. The cable arrives in secure 10x10x10 case packaging to ensure connector protection. Choose the JBX42687 for reliable, standards-compliant fiber optic connectivity that professional networks demand.
