The JBX43471 50-meter FC/APC to FC/APC simplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical fiber optic installations. This single-strand simplex cable is specifically designed for unidirectional signal transmission in applications requiring dedicated optical pathways. **Technical Specifications:** Built with 9/125 singlemode fiber cores and G.657.A1 glass technology, this cable achieves exceptional optical performance. Attenuation specifications of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm ensure minimal signal loss over extended runs. The measured insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB exceed industry standards for telecommunications-grade applications. **Connector Quality:** FC/APC connectors feature angled polished surfaces that minimize back-reflections and provide superior signal integrity compared to standard connectors. The straight-through polarity configuration ensures reliable signal transmission in one direction, making this cable ideal for single-channel applications. **Safety & Compliance:** The yellow OFNR (Optical Fiber Non-conductive Riser) jacket meets fire-safety codes required in commercial buildings and data centers. TAA compliant and RoHS/ELV certified, this cable meets government procurement standards. Manufactured in Taiwan, the United States, or China, this product maintains consistent quality across all production facilities. **Practical Advantages:** With an outside diameter of just 1.8mm, installation flexibility rivals copper cables while eliminating electromagnetic interference. The compact packaging (10x10x10 case) facilitates bulk ordering and storage. Available in custom lengths beyond the standard 50m for specialized installations. **Applications:** Ideal for telecommunications networks, data center interconnects, server room installations, and test/measurement equipment connections. The TAA compliance makes it suitable for government contracts and security-sensitive deployments. **Warranty & Support:** Backed by a 90-day limited warranty ensuring peace of mind. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99.
