The JBX42422 1.5-meter FC/APC to FC/UPC duplex singlemode fiber patch cable represents a premium solution for fiber optic network connectivity in telecommunications, data centers, and enterprise environments. This professionally-engineered cable meets stringent industry standards and government compliance requirements, making it suitable for mission-critical applications where reliability and performance are paramount. **Technical Excellence:** Built with genuine 9/125 singlemode fiber (G.657.A1 specification), this duplex patch cable delivers exceptional optical performance. The cable achieves insertion loss of ≤0.35dB with typical performance of just 0.15dB, and maintains return loss exceeding 20dB—critical metrics for signal integrity. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure optimal performance across standard telecommunications wavelengths. **Connector Configuration:** The FC/APC to FC/UPC crossover configuration (Type A to B polarity) is the industry standard for duplex patch cords, ensuring compatibility with existing network infrastructure. FC (Ferrule Connector) connectors are renowned for their durability and precision in high-reliability applications, while the APC/UPC pairing accommodates cross-connector requirements in modern networks. **Government & Compliance Standards:** This cable is TAA (Trade Agreements Act) compliant, meeting Federal procurement requirements for government contracts. Full RoHS/ELV directive compliance (EU 2002/95/EC) ensures environmental responsibility without compromising performance. Manufacturing locations in Taiwan, US, and China provide supply chain flexibility. **Physical Specifications:** The 1.8mm outside diameter with OFNR (Optical Fiber Non-Conductive Riser) rated yellow jacketing provides flame resistance and easy identification in color-coded installations. The 1.5-meter length suits typical rack-to-rack and equipment-level interconnections. Custom length availability accommodates non-standard requirements. **Practical Applications:** Ideal for fiber-to-the-desk (FTTD), telecom central offices, cable television (CATV) headends, medical imaging systems, and high-speed data transmission networks. The duplex configuration enables bidirectional communication over two separate fiber strands. **Quality Assurance:** Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, backed by a 90-day limited warranty. Ships from multiple US locations (California, Texas, South Carolina) with free standard shipping on orders exceeding $99, ensuring quick delivery and reliable logistics for critical installations.
