The JBX42023 is a professional 60-meter LC/APC to LC/UPC duplex single mode fiber patch cable engineered for high-performance network infrastructure. This cable is essential for data centers, telecommunications facilities, and enterprise network environments requiring extended-distance fiber connectivity with minimal signal degradation. **Key Technical Specifications:** This duplex patch cable features a 9/125 single mode core with G.657.A1 grade glass fiber, delivering exceptional optical performance. The LC/APC to LC/UPC configuration represents a Type A to B crossover polarity, the most common duplex patch cord standard. Measured insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB exceed industry standards for signal integrity. Attenuation ratings of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm ensure reliable long-distance transmission. **Build Quality and Compliance:** The cable features OFNR (Optical Fiber Non-conductive Riser) rated yellow jacket with 1.8mm outer diameter, providing durability and fire safety. Full RoHS/ELV and EU Directive 2002/95/EC compliance ensures environmental responsibility. TAA compliance makes it ideal for government and defense applications. **Installation and Flexibility:** Available in custom lengths beyond the standard 60m, this cable accommodates diverse installation requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for quick delivery. Free standard shipping on orders exceeding $99 provides excellent value. **Ideal Applications:** Perfect for data center interconnects, LAN/WAN installations, fiber-to-the-premises (FTTP) networks, and telecommunications infrastructure. The 60-meter length bridges significant distances while maintaining signal quality, making it essential for large facility deployments. **Warranty and Support:** Backed by a 90-day limited warranty, this cable provides peace of mind for critical network installations. Professional-grade construction ensures reliable long-term performance.
