The JBX42686 75m FC/APC to LC/UPC duplex singlemode fiber patch cable represents professional-grade optical connectivity engineered for demanding network environments. Whether you're upgrading a data center, expanding telecommunications infrastructure, or establishing long-distance network links, this cable delivers consistent, reliable performance. Optical Performance Excellence: With an insertion loss of just 0.15dB typical (≤0.35dB maximum), this patch cable minimizes signal degradation over its 75-meter span. The return loss specification of ≥20dB ensures signal integrity and reduces reflections that could impact network performance. These specifications are verified through rigorous ANSI/TIA/EIA-455-171-A-2001 testing protocols, guaranteeing consistent quality across production batches. Connector Configuration: The FC/APC to LC/UPC configuration bridges two industry-standard connector types, enabling seamless integration with diverse equipment. FC/APC connectors feature angled physical contact design, delivering superior return loss characteristics. LC/UPC connectors provide compact form factors ideal for high-density patch panels. The Type A to B crossover polarity configuration represents the most common duplex installation standard, simplifying deployment while reducing installation errors. Construction & Durability: Constructed with G.657.A1 glass fiber, this cable provides enhanced bend performance suitable for modern network installations where space optimization is critical. The 9/125 singlemode core enables transmission across extended distances without modal dispersion. The 1.8mm outer diameter offers flexibility for routing through conduits and cable trays. OFNR riser-rated jacketing ensures compliance with building codes for vertical cable runs within structures. Compliance & Standards: TAA compliance makes this cable eligible for government and institutional procurement programs. RoHS/ELV certification confirms environmental responsibility and regulatory adherence. The cable meets harmonization code 8544.70.0000 specifications, qualifying for international trade and procurement. Applications: Ideal for telecommunications networks, enterprise data centers, campus network installations, and carrier-class infrastructure projects. The extended 75-meter length supports backbone connections, floor-to-floor routing, and building-to-building links. The distinctive yellow jacket provides quick visual identification in complex cable environments. Available in custom lengths for unique project requirements.
