The JBX43542 ST/APC to FC/UPC simplex fiber patch cable represents professional-grade connectivity solutions for critical network infrastructure. This 1.5-meter cable combines ST/APC and FC/UPC connectors in a single-strand configuration, offering versatility for diverse telecommunications and data center applications. Key Technical Specifications: This singlemode fiber cable features a precise 9/125 micron core with G.657.A1 glass fiber, delivering industry-leading performance metrics. The insertion loss specification of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB ensure minimal signal degradation across transmission wavelengths. Attenuation testing at 1310nm achieves 0.25dB/km, while 1550nm operates at 0.35dB/km, meeting ANSI/TIA/EIA-455-171-A standards. Construction and Durability: The cable features a yellow OFNR (Optical Fiber, Nonconductive, Riser Rated) jacket that provides flame resistance and safety compliance. The 1.8mm outside diameter balances protection with space efficiency in cable conduits. RoHS and ELV compliance ensures environmental safety, while TAA compliance supports government and institutional procurement requirements. Applications and Use Cases: Ideal for connecting telecommunications equipment, data center infrastructure, FTTH (Fiber to the Home) installations, and broadcast facilities. The straight-through polarity configuration simplifies installation workflows. The distinctive yellow coloring aids in network documentation and troubleshooting. Customization and Support: Custom length availability accommodates non-standard installation requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. The 90-day limited warranty provides peace of mind for critical deployments. All specifications are tested and verified to ensure reliable performance in demanding environments.
