The JBX42626 FC/APC to ST/UPC duplex singlemode fiber patch cable represents a premium solution for telecommunications professionals, network administrators, and data center operators requiring reliable long-distance fiber optic connectivity. At 75 meters, this cable is engineered to maintain signal integrity over extended runs while minimizing optical loss and maintaining superior return loss characteristics. Technical Excellence: Constructed with 9/125 singlemode fiber and G.657.A1 glass core, this duplex patch cable meets rigorous industry standards for optical performance. Independent testing confirms insertion loss of ≤0.35dB (typically 0.15dB) and return loss exceeding 20dB, with attenuation specifications of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm. These specifications ensure minimal signal degradation, critical for maintaining network performance across long cable runs. Connector Configuration: The FC/APC (Angled Physical Contact) to ST/UPC (Straight) crossover configuration provides Type A to B polarity—the most common duplex arrangement used in telecommunications infrastructure. This combination enables seamless integration with existing network architectures while maintaining optimal signal transmission between different connector types. Build Quality & Compliance: Featuring a durable 1.8mm diameter cable with OFNR riser-rated jacketing, this patch cable meets demanding building code requirements and environmental standards. The distinctive yellow jacket enhances visibility and organization within cable management systems. Full TAA compliance and RoHS/ELV certification ensure regulatory adherence for government and enterprise procurement. Applications: • Telecommunications network backbone connections • Data center infrastructure deployments • Campus area network (CAN) implementations • Telecommunications equipment interconnection • High-speed signal transmission environments Flexibility & Service: Available in custom lengths to accommodate specific installation requirements, this cable adapts to diverse network topologies. Ships from strategically located US warehouses with free standard shipping on orders exceeding $99. The 90-day limited warranty provides peace of mind, backed by professional technical support. Maintenance & Care: Store coiled loosely without sharp bends exceeding the cable's bend radius specifications. Clean connectors with appropriate fiber optic cleaning solutions before connection. Protect connectors with dust caps when not in use to prevent contamination and maintain optimal signal quality.
