The JBX43349 40-meter SC/APC to FC/APC simplex fiber patch cable represents a premium solution for professional networking infrastructure. Designed to bridge SC/APC and FC/APC connectors, this singlemode optical cable delivers exceptional performance for telecommunications, data centers, and enterprise network environments. **Technical Excellence** This cable features 9/125 singlemode fiber construction with G.657.A1 glass fiber specification, specifically engineered for bend-insensitive applications without sacrificing performance. The measured insertion loss of ≤0.35dB (typical 0.15dB at both 1310nm and 1550nm wavelengths) ensures minimal signal degradation, while the return loss of ≥20dB maintains signal integrity across your network backbone. **Durability and Compliance** Constructed with 1.8mm outside diameter jacketing rated OFNR (Riser), the cable meets rigorous fire safety standards for building installations. Full RoHS/ELV compliance ensures environmental responsibility, while TAA compliance meets U.S. federal procurement requirements. The simplex (single fiber strand) design simplifies installation in unidirectional signal applications. **Practical Advantages** The distinctive yellow jacketing provides clear visual identification in complex cable runs, reducing installation and troubleshooting time. At 40 meters, this cable bridges moderate distances between equipment racks, patch panels, and network devices without requiring intermediate splitters or boosters. **Customization and Support** Beyond the standard 40-meter offering, custom lengths are available to precisely match your infrastructure requirements. The 90-day limited warranty provides confidence in product reliability, while multiple U.S. shipping locations ensure prompt delivery. **Applications** Ideal for telecommunications facilities, data center interconnects, DWDM systems, and enterprise backbone installations where signal fidelity is paramount. The SC/APC to FC/APC connector combination accommodates diverse equipment from leading network manufacturers. Ships with free standard delivery on orders exceeding $99, making enterprise-grade fiber connectivity accessible and economical.
