The JBX42206 75-meter LC/APC to FC/UPC duplex singlemode fiber patch cable represents professional-grade connectivity engineered for demanding telecommunications and data center environments. This cable delivers exceptional performance through its G.657.A1 glass fiber specification, which provides superior macrobending performance while maintaining low attenuation across critical wavelengths. **Technical Excellence:** With a 9/125 singlemode core, this cable enables precise signal transmission over extended distances with minimal loss. Attenuation specifications of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm ensure reliable performance for both traditional and CWDM applications. The typical insertion loss of just 0.15dB and return loss ≥20dB provide the signal integrity required for mission-critical networks. **Connectivity Design:** The LC/APC to FC/UPC connector combination offers industry-standard compatibility, while the Type A to B crossover polarity ensures optimal signal transmission in duplex configurations. The 1.8mm outside diameter provides flexibility in installation while maintaining durability through the riser-rated (OFNR) jacketing. **Compliance & Quality:** Fully TAA compliant and manufactured in accordance with ANSI/TIA/EIA standards, this cable meets stringent government procurement requirements. RoHS/ELV compliant with EU Directive 2002/95/EC certification, ensuring environmental responsibility. Backed by a 90-day limited warranty and available in custom lengths for specialized installations. **Practical Benefits:** The bright yellow jacket facilitates rapid cable identification and organization in complex network installations. Available with free standard shipping on orders over $99, with convenient fulfillment from multiple US distribution centers in California, Texas, and South Carolina. Custom length options accommodate unique installation requirements beyond the standard 75-meter specification. **Ideal Applications:** Perfect for telecommunications backbone connections, data center interconnects, long-distance signal transmission, and any application requiring reliable singlemode fiber connectivity with excellent attenuation characteristics.
