The JBX43429 FC/APC to FC/UPC Simplex Singlemode Fiber Patch Cable represents a professional-grade solution for high-performance optical fiber network installations. Manufactured to exacting standards using G.657.A1 glass fiber, this 7-meter cable is specifically designed for applications requiring single-strand, unidirectional signal transmission in telecommunications, data centers, and enterprise network infrastructure. **Technical Excellence** With a 9/125 micron core and cladding configuration, this singlemode fiber delivers superior long-distance transmission capabilities with minimal attenuation. The cable's insertion loss specification of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while the return loss of ≥20dB prevents signal reflections that could compromise data integrity. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm meet rigorous telecommunications standards. **Professional Installation Features** The FC/APC connector type on one end and FC/UPC on the other enables straightforward connections in mixed environments while maintaining optimal optical performance. The 1.8mm outer diameter facilitates installation in space-constrained environments, conduits, and cable trays. OFNR riser-rated jacketing ensures compliance with building safety codes for plenum installations. **Compliance and Quality Assurance** TAA (Trade Agreements Act) compliance makes this cable suitable for U.S. government and federal agency procurement. RoHS/ELV directive compliance ensures environmental responsibility and future-proofing. All cables are attenuation-tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality across production batches. The 90-day limited warranty provides purchase confidence. **Customization and Availability** This cable is available in custom lengths for non-standard installation requirements. Multiple domestic fulfillment locations (California, Texas, and South Carolina) enable rapid deployment. Free standard shipping on orders exceeding $99 provides cost-effective procurement for bulk installations. **Applications** Ideal for telecommunications backbone connections, data center patching, equipment interconnects, and any installation requiring reliable, low-loss singlemode fiber transmission. The yellow outer sheath provides visual identification for network management and troubleshooting.
