The JBX42660 FC/APC to LC/UPC duplex singlemode fiber patch cable represents a professional-grade solution for mission-critical network infrastructure. Engineered with precision manufacturing standards, this 0.5-meter cable delivers exceptional performance in demanding telecommunications, data center, and enterprise networking environments. Advanced Fiber Technology Constructed with 9/125 singlemode fiber featuring G.657.A1 glass composition, this cable supports high-bandwidth applications across standard telecommunications wavelengths. The singlemode design eliminates modal dispersion, enabling superior signal quality over extended distances. With attenuation ratings of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm, the cable performs optimally across critical network frequencies. Connector Configuration The FC/APC (ferrule connector with angled physical contact) to LC/UPC (local connector with ultra-physical contact) configuration provides maximum versatility for connecting different network components. Type A to B crossover polarity ensures proper signal transmission in duplex applications, supporting bidirectional communication essential for modern network operations. Performance Specifications Measured insertion loss of ≤0.35dB (typical 0.15dB) minimizes signal degradation, while return loss of ≥20dB exceeds industry standards for reliable data transmission. All specifications are independently verified through rigorous testing protocols, ensuring consistent quality across production batches. Installation & Reliability The compact 1.8mm diameter jacketing with OFNR (riser-rated) material rating facilitates installation in conduits and cable trays while maintaining safety compliance. The distinctive yellow jacket enables quick identification in complex cable management scenarios. Custom length options accommodate unique installation requirements beyond the standard 0.5m configuration. Compliance & Certification TAA (Trade Agreements Act) compliance qualifies this cable for government and federal procurement programs. RoHS and ELV directive compliance (EU directive 2002/95/EC) demonstrate commitment to environmental responsibility without compromising performance. A 90-day limited warranty provides peace of mind for critical installations. Applications Ideal for telecommunications networks, fiber-to-the-premises (FTTP) installations, data center interconnects, and enterprise network upgrades. Suitable for both new installations and replacements in existing infrastructure. Ships promptly from multiple US locations with free standard shipping on qualifying orders.
