The JBX43487 ST/APC to ST/UPC Simplex Singlemode Fiber Patch Cable represents an excellent solution for professionals requiring dependable optical connectivity. Manufactured to exacting standards, this 5-meter cable is specifically designed for applications where precise signal transmission is critical. **Technical Excellence** This cable features a 9/125 singlemode core that supports wavelengths at both 1310nm and 1550nm, making it versatile for various telecommunications applications. The measured attenuation of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensures minimal signal loss over distance. With insertion loss rated at ≤0.35dB (0.15dB typical) and return loss ≥20dB, performance metrics exceed industry standards tested per ANSI/TIA/EIA-455-171-A-2001. **Compliance and Safety** TAA compliant status makes this cable eligible for federal government purchases and GSA schedules. RoHS/ELV certification and EU Directive 2002/95/EC compliance ensure environmental responsibility. The OFNR (Optical Fiber Non-conductive Riser) jacket rating permits installation in vertical cable runs within buildings without conduit. **Practical Design Features** The distinctive yellow jacket facilitates quick identification among multiple cables, reducing installation time and maintenance errors. The 1.8mm outside diameter provides a balance between flexibility and durability, while the G.657.A1 glass fiber composition offers bend-insensitive characteristics ideal for challenging installation environments. **Versatile Application** Perfect for data centers, telecommunications facilities, campus networks, and fiber-to-the-premises installations. The ST/APC to ST/UPC configuration accommodates mixed-connector environments common in network upgrades and hybrid systems. **Warranty and Support** Backed by a 90-day limited warranty. Available in custom lengths for specialized applications. Ships from multiple US locations (California, Texas, South Carolina) with free standard shipping on orders exceeding $99.
