The JBX43189 7-meter LC/APC to FC/UPC simplex fiber patch cable represents professional-grade connectivity for demanding telecommunications infrastructure. This carefully engineered cable bridges the gap between two critical connector types used across the industry, making it essential for equipment interconnection in diverse network environments. **Technical Excellence** Built with 9/125 singlemode fiber and G.657.A1 glass composition, this cable delivers exceptional optical performance. The LC/APC (angled physical contact) connector provides superior return loss characteristics, while the FC/UPC (ultra-polished connector) offers industry-standard connectivity. With insertion loss of ≤0.35dB and return loss ≥20dB, this cable minimizes signal degradation across standard telecommunications wavelengths (1310nm and 1550nm). **Design and Construction** The simplex design transmits signals in one direction, making it ideal for applications requiring dedicated send or receive paths. The outer diameter of 1.8mm provides optimal balance between flexibility and durability, while the OFNR riser rating ensures compliance with building safety codes for in-building installations. The distinctive yellow jacket facilitates cable identification and organization in complex network environments. **Compliance and Standards** TAA-compliant certification makes this cable suitable for government contracts and institutional procurement. Full compliance with RoHS/ELV directives ensures environmental responsibility. All products are tested according to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistency and reliability. **Practical Advantages** Shipped from multiple U.S. locations (Danville CA, Fort Worth TX, and Beaufort SC), this cable qualifies for free standard shipping on orders exceeding $99. Custom length availability accommodates specialized installation requirements. The 90-day limited warranty provides peace of mind for your investment. **Applications** Ideal for telecommunications installations, data centers, optical test equipment setups, and enterprise networks requiring reliable fiber optic connectivity between different connector types.
