The JBX42627 80-meter FC/APC to ST/UPC duplex singlemode fiber patch cable represents the ideal solution for professional network installations requiring extended reach with superior signal integrity. This industrial-grade optical cable combines precision engineering with cost-effective performance across long-distance applications. **Technical Excellence** Built with 9/125 singlemode fiber and G.657.A1 glass fiber technology, this cable delivers attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. Testing confirms insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, meeting ANSI/TIA/EIA-455-171-A-2001 standards. The dual-strand duplex design enables simultaneous bidirectional communication with Type A to B crossover configuration—the industry standard for most patch cord applications. **Durability and Compliance** The cable features OFNR (Optical Fiber Non-conductive Riser) jacketing suitable for in-building use, with 1.8mm outer diameter for flexible routing in conduits and cable trays. RoHS and ELV compliant manufacturing ensures environmental responsibility. TAA compliance qualifies this cable for government and institutional procurement. Multiple US manufacturing and distribution points (Danville CA, Fort Worth TX, Beaufort SC) ensure rapid fulfillment. **Practical Advantages** The distinctive yellow jacket simplifies cable identification during installation and maintenance, reducing configuration errors in complex environments. Custom length availability accommodates unique network layouts beyond the standard 80m specification. The 90-day limited warranty protects your investment, while free standard shipping on orders exceeding $99 delivers exceptional value. **Ideal Applications** Perfect for data centers, telecommunications facilities, university campuses, and enterprise networks where extended-distance connectivity demands maximum reliability. Compatible with FC/APC and ST/UPC equipped network equipment including patch panels, switches, and optical distribution frames. Choose the JBX42627 for professional-grade performance, standards compliance, and long-term reliability in mission-critical fiber optic installations.
