The JBX42013 12-meter LC/APC to LC/UPC duplex single mode fiber patch cable is engineered for mission-critical network applications requiring exceptional signal integrity and reliability. This professional-grade component combines precision fiber optics with robust construction to deliver consistent performance in demanding telecommunications and data center environments. Technical Excellence: Built with 9/125 single mode fiber (G.657.A1), this cable provides superior signal propagation characteristics. The LC/APC to LC/UPC connector configuration implements a Type A to B crossover polarity—the industry standard for duplex patch cord applications. With insertion loss of just ≤0.35dB (0.15dB typical) and return loss exceeding 20dB, attenuation performance meets or exceeds ANSI/TIA/EIA-455-171-A standards for both 1310nm and 1550nm wavelengths. Durable Construction: The 1.8mm diameter riser-rated (OFNR) yellow jacket provides flame resistance while offering excellent identification in complex installations. The duplex configuration enables simultaneous bidirectional communication, maximizing throughput efficiency. RoHS/ELV compliant materials ensure environmental responsibility and regulatory compliance across global markets. Versatile Applications: Perfect for connecting network switches, routers, and fiber distribution panels. Ideal for campus networks, data center interconnects, telecommunications closets, and long-distance transmission links. The 12-meter length accommodates medium-distance runs while maintaining signal quality. Convenience & Support: TAA compliant for government and institutional procurement. Available in custom lengths to fit specific installation requirements. Manufactured with multi-source capability (TW, US, CN) ensuring supply reliability. Ships from multiple U.S. locations for faster delivery. 90-day limited warranty provides peace of mind. Value Proposition: Premium performance at competitive pricing with free standard shipping on orders over $99. Choose the JBX42013 for professional-grade fiber connectivity backed by industry standards and proven reliability.
