The JBX42674 FC/APC to LC/UPC duplex singlemode fiber patch cable represents enterprise-class connectivity for demanding telecommunications and data center applications. This 15-meter cable assembly combines precision engineering with industry-leading performance specifications. Technical Excellence: Constructed with 9/125 singlemode fiber and G.657.A1 grade glass, this cable delivers superior attenuation performance (0.25 dB/km at 1310nm; 0.35 dB/km at 1550nm) meeting ANSI/TIA/EIA-455-171-A-2001 standards. The duplex configuration with Type A to B crossover polarity enables efficient bidirectional communication, making it ideal for interconnecting network equipment, telecom infrastructure, and fiber-to-the-premises (FTTP) installations. Connector Specifications: The FC/APC (FC Angled Physical Contact) connector on one end connects to LC/UPC (Lucent Connector Unangled Physical Contact) on the other, providing flexibility in mixed-connector network environments. Both connector types feature factory-tested insertion loss of ≤0.35dB and return loss ≥20dB, ensuring minimal signal degradation. Build Quality & Compliance: Features riser-rated (OFNR) jacketing rated for indoor plenum and non-plenum installations. RoHS/ELV compliant and TAA-certified, meeting government procurement requirements. The 1.8mm diameter jacketing with flexible design allows for easy cable management without exceeding bend-radius specifications, even in tight installation spaces. Applications: Ideally suited for enterprise networks, telecommunications carrier networks, data center interconnects, college and university campus networks, and government facility installations. The yellow jacket provides quick visual identification in crowded cable environments. Custom Solutions Available: While this cable ships at 15 meters, custom lengths are available for specific project requirements. Ships from multiple U.S. locations (Danville, CA; Fort Worth, TX; Beaufort, SC) with free standard shipping on orders over $99. Warranty & Support: 90-day limited warranty covers manufacturing defects. Product manufactured in Taiwan, United States, or China per supply chain optimization.
