The JBX43337 5m SC/APC to FC/APC Simplex 9/125 Singlemode Fiber Patch Cable represents a professional-grade solution for organizations requiring dependable fiber optic connectivity in telecommunications, data center, and network infrastructure environments. **Technical Specifications:** Constructed with 9/125 singlemode fiber operating at both 1310nm and 1550nm wavelengths, this cable delivers exceptional performance with attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm. The measured insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB exceed industry standards for signal integrity. The G.657.A1 fiber grade provides superior bend resistance while maintaining optical performance. **Design and Construction:** The simplex configuration provides unidirectional signal transmission through a single fiber strand, making it ideal for applications requiring dedicated transmission or reception paths. SC/APC and FC/APC connectors feature angle-polished ferrules that minimize back-reflection and signal degradation. The 1.8mm outside diameter and flexible 5-meter length accommodate diverse installation scenarios from compact server cabinets to distributed network deployments. **Compliance and Certification:** Fully TAA compliant and certified to RoHS/ELV directives (EU 2002/95/EC), this cable meets stringent procurement requirements for government agencies and enterprise customers. OFNR riser-rated jacketing ensures fire safety for in-wall and inter-floor installations. Manufacturing in Taiwan, the United States, and China provides supply chain flexibility and reliable availability. **Applications:** Ideal for point-to-point fiber connections in telecommunications equipment, optical testing and measurement, network infrastructure expansion, and enterprise-grade data transmission. The APC connector angle-polishing reduces back-reflection critical for sensitive applications. **Custom Solutions:** Available in custom lengths beyond the standard 5-meter configuration to optimize installation efficiency and cable management. Ships from multiple domestic warehouses in California, Texas, and South Carolina for expedited delivery. Backed by a 90-day limited warranty and standard shipping included on orders exceeding $99.
