The JBX43374 15-meter SC/APC to ST/UPC simplex fiber patch cable represents professional-grade connectivity engineered for critical network infrastructure. This cable is manufactured to rigorous standards and tested for attenuation compliance with ANSI/TIA/EIA-455-171-A-2001, ensuring reliable performance in demanding telecommunications applications. **Technical Specifications:** Constructed with a 9/125 singlemode core utilizing G.657.A1 glass fiber technology, this cable achieves exceptional optical performance. The insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB meet or exceed industry standards. Attenuation measurements of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm provide excellent signal transmission across extended distances. **Connector Configuration:** The SC/APC to ST/UPC simplex design enables straightforward connectivity between equipment using different connector types. The straight-through polarity configuration ensures proper signal alignment without requiring adapter switches. This configuration is particularly valuable in hybrid network environments or when integrating legacy systems with modern infrastructure. **Compliance & Safety:** TAA compliance makes this cable eligible for federal government procurement and projects with stringent supply chain requirements. RoHS/ELV certification confirms environmental safety and regulatory adherence. The OFNR riser rating permits installation in vertical spaces between floors without requiring conduit protection, simplifying deployment in multi-story buildings. **Durability & Reliability:** Manufactured with plastic accessories and precision-engineered components, the cable provides robust durability in professional settings. The 1.8mm outside diameter balances flexibility with protection, preventing kinks while remaining manageable during installation. A 90-day limited warranty provides additional peace of mind for critical installations. **Customization & Convenience:** While the standard 15-meter length covers most applications, custom lengths are available for specialized projects. Free standard shipping on orders exceeding $99 reduces procurement costs. Multiple fulfillment centers in Danville CA, Fort Worth TX, and Beaufort SC ensure rapid delivery nationwide. **Applications:** Ideal for data centers, telecommunications facilities, broadcast studios, and any installation requiring reliable singlemode fiber connectivity with mixed connector types. Perfect for upgrading legacy systems or integrating equipment from different manufacturers.
