The JBX42185 3-meter LC/APC to FC/UPC duplex singlemode fiber patch cable represents enterprise-grade connectivity for demanding telecommunications and data center applications. Manufactured with precision tolerances and rigorous quality testing, this cable ensures reliable signal transmission and minimal signal degradation. Technical Excellence: This fiber patch cable features G.657.A1 singlemode fiber with a 9/125 micron core/cladding ratio, specifically designed for long-distance, high-bandwidth applications. The duplex configuration supports bidirectional data transmission on a single cable run, reducing installation complexity. With measured insertion loss of just 0.15dB (typical) and return loss exceeding 20dB, this cable meets or exceeds industry standards for professional network installations. Connector Specifications: The LC/APC (Angled Physical Contact) termination on one end and FC/UPC (Ultra Physical Contact) on the other provide a Type A to B crossover configuration—the most common polarity standard for duplex patch cords. This cross-polarity design is ideal for network switches, telecommunications equipment, and DWDM systems. Build Quality and Compliance: The yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket provides fire resistance and flame retardancy suitable for in-building backbone applications. TAA compliance ensures this cable meets federal procurement requirements. RoHS and ELV directive compliance confirms environmental responsibility. The robust 1.8mm outer diameter resists kinking while maintaining flexibility for routing through tight spaces. Applications and Use Cases: • Data center uplink connections • Telecommunications backbone networks • DWDM system installations • Government and institutional networks (TAA compliance) • High-speed WAN connections • Network testing and measurement systems Reliability and Support: Each cable is tested according to ANSI/TIA/EIA-455-171-A-2001 standards at both 1310nm and 1550nm wavelengths, ensuring consistent performance. The 90-day limited warranty provides peace of mind, while free standard shipping on qualifying orders makes enterprise-grade connectivity affordable. Available in custom lengths for non-standard installations. Choose the JBX42185 for professional-grade fiber connectivity that delivers superior signal integrity, compliance certifications, and proven reliability in mission-critical network environments.
