The JBX42682 55-meter FC/APC to LC/UPC duplex singlemode fiber patch cable represents a premium solution for enterprise-grade optical network installations requiring precision connectivity and reliable performance. This cable combines advanced fiber technology with practical design features to deliver exceptional value for data centers, telecommunications infrastructure, and high-speed network deployments. Key Performance Specifications: Construction with 9/125 singlemode fiber and G.657.A1 glass composition ensures superior signal integrity across extended distances. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm meet stringent industry standards, while insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB guarantee optimal optical coupling efficiency. Testing conducted per ANSI/TIA/EIA-455-171-A-2001 standards confirms performance reliability. Design and Installation Benefits: The duplex configuration with Type A to B crossover polarity enables bidirectional signal transmission on a single cable run, reducing installation complexity. The bright yellow outer jacket with 1.8mm diameter facilitates easy identification and routing through cable trays and conduit systems. OFNR (Riser) rated jacketing ensures building code compliance for in-wall installations. Compliance and Quality Assurance: TAA compliant design meets federal procurement requirements, while RoHS/ELV directive adherence ensures environmental responsibility. The 90-day limited warranty provides confidence in product reliability. Custom length options accommodate specific deployment scenarios beyond the standard 55-meter configuration. Ideal for telecommunications carriers, ISPs, enterprise data centers, and network service providers requiring robust, future-proof fiber infrastructure.
