The JBX43668 LC/UPC to FC/APC Simplex Singlemode Fiber Patch Cable represents a premium solution for professional optical network infrastructure. This 6-meter cable combines precision engineering with compliance standards required for government and enterprise environments. **Technical Excellence** Built on 9/125 singlemode core fiber technology with G.657.A1 specification, this cable meets the most stringent performance requirements. The insertion loss specification of ≤0.35dB (typical 0.15dB) ensures minimal signal degradation, while the return loss of ≥20dB provides excellent signal integrity. Attenuation testing confirms performance at both 1310nm (0.25dB/km) and 1550nm (0.35dB/km) wavelengths, supporting modern DWDM applications. **Compliance and Quality** TAA compliance makes this cable ideal for government procurement, GSA contracts, and vendors serving federal accounts. RoHS/ELV certification demonstrates environmental responsibility and compliance with EU directives. The cable undergoes rigorous testing per ANSI/TIA/EIA-455-171-A standards, ensuring reliability in critical applications. **Design Features** The simplex configuration transmits signals in a single direction, making it perfect for point-to-point connections where dedicated unidirectional paths are required. The distinctive yellow jacket enables quick identification in crowded data center environments, while the 1.8mm outside diameter provides excellent bend radius characteristics. Riser-rated (OFNR) jacketing ensures fire safety compliance in building installations. **Flexibility and Support** Custom lengths are available to meet specific installation requirements. Ships from multiple U.S. locations (California, Texas, South Carolina) with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty for peace of mind. **Applications** Ideal for telecom networks, data centers, FTTH installations, and laboratory environments where high-performance singlemode connectivity is essential. The LC/UPC to FC/APC configuration accommodates diverse equipment compatibility needs in mixed-vendor environments.
