The JBX43490 8-meter ST/APC to ST/UPC Simplex Singlemode Fiber Patch Cable represents premium connectivity solutions for professional networking environments. This carefully engineered cable combines precision optics with robust construction to deliver superior performance in demanding telecommunications and data center applications. Technical Excellence: The cable features a 9/125 singlemode core with advanced G.657.A1 glass fiber technology, optimized for both 1310nm and 1550nm wavelengths. With attenuation of just 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm, this cable minimizes signal loss over longer distances. The insertion loss specification of ≤0.35dB (0.15dB typical) and return loss ≥20dB ensure exceptional optical performance that meets or exceeds enterprise standards. Connector Configuration: The ST/APC to ST/UPC configuration provides hybrid connectivity flexibility, allowing seamless integration into mixed networking environments. APC (Angled Physical Contact) connectors feature ultra-low back-reflection characteristics ideal for sensitive applications, while UPC (Ultra Physical Contact) connectors offer standard performance at receiver endpoints. Construction & Compliance: The 1.8mm outside diameter yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket provides fire-safe operation in indoor installations while maintaining flexibility for cable routing. TAA compliance and RoHS/ELV certification ensure compatibility with government and enterprise procurement requirements. The cable is manufactured to exacting standards verified through ANSI/TIA/EIA-455-171-A testing protocols. Applications & Benefits: Ideal for telecommunications closets, data center interconnects, LAN deployments, and fiber-to-the-premises installations. The simplex design focuses on single-direction signal transmission for specialized point-to-point connections. Custom lengths available for unique installation requirements. Warranty & Support: Backed by a comprehensive 90-day limited warranty, with free standard shipping on orders over $99. Ships from multiple US distribution centers for expedited delivery.
