The JBX42025 70-meter LC/APC to LC/UPC duplex single mode fiber patch cable represents a professional-grade solution for high-speed data transmission in critical network infrastructure. This optical cable combines precision engineering with reliability, making it an ideal choice for telecommunications facilities, data centers, ISP networks, and enterprise-grade installations. Technical Specifications & Performance: This duplex patch cable features a 9/125 single mode core with G.657.A1 glass fiber construction, optimized for long-distance signal transmission with minimal signal degradation. The cable delivers exceptional performance metrics: insertion loss of ≤0.35dB at typical 0.15dB, return loss ≥20dB, and attenuation of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm. These specifications ensure reliable performance for both traditional and modern wavelength division multiplexing applications. Durable Construction & Installation: The yellow OFNR (Optical Fiber Non-conductive Riser) jacket provides both visual identification and safety compliance for in-building applications. With a compact 1.8mm outside diameter, this cable easily routes through cable trays, conduits, and tight spaces without compromising performance. The LC/APC to LC/UPC connector configuration represents the industry-standard Type A to B crossover polarity, ensuring seamless compatibility with existing network infrastructure. Compliance & Certifications: Fully TAA-compliant and certified to RoHS/ELV directives (EU 2002/95/EC), this cable meets government procurement requirements and environmental standards. Performance testing adheres to ANSI/TIA/EIA-455-171-A standards, guaranteeing consistent quality across production batches. Applications: Perfect for data center interconnects, telecommunications backbone networks, fiber-to-the-premises installations, and network upgrades requiring reliable, long-distance connectivity. The 70-meter length accommodates medium to large facility deployments. Warranty & Support: Backed by a 90-day limited warranty and available in custom lengths upon request.
