The JBX43128 SC/APC to SC/UPC simplex fiber patch cable represents a professional-grade solution for telecommunications infrastructure, data center connectivity, and enterprise networking applications. This 6-meter cable delivers superior optical performance with precision-engineered connectors and high-quality singlemode fiber. **Technical Specifications:** This simplex configuration features 9/125 micron core/cladding singlemode fiber optimized for long-distance signal transmission. The cable incorporates G.657.A1 glass fiber technology, providing excellent bend-radius performance without sacrificing signal quality. With an outside diameter of just 1.8mm, the cable offers excellent space efficiency in tight installation scenarios. **Performance Metrics:** Tested to ANSI/TIA/EIA-455-171-A standards, the cable delivers insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB. Attenuation specifications include 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, ensuring optimal signal integrity across critical wavelengths. **Standards Compliance:** Fully TAA compliant for federal procurement, this cable meets RoHS/ELV directives and includes EU directive 2002/95/EC compliance. The OFNR riser rating allows installation in building plenum spaces, while yellow jacketing provides superior visibility for identification and troubleshooting. **Applications:** Ideal for telecommunications networks, enterprise data centers, telecommunications test labs, and high-performance computing environments requiring reliable single-strand fiber connectivity between SC/APC and SC/UPC endpoints. **Custom Solutions:** Available in custom lengths to accommodate specific installation requirements beyond the standard 6-meter configuration. Ships from multiple US locations with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty for peace of mind.
