The JBX43453 FC/APC to FC/APC simplex singlemode fiber patch cable represents the gold standard for high-performance optical connectivity. This 2-meter cable features a precision-engineered 9/125 singlemode core with G.657.A1 glass fiber, optimized for long-distance signal transmission in telecommunications, ISP, and enterprise data center applications. **Superior Optical Performance** This singlemode fiber cable delivers exceptional transmission characteristics with insertion loss of ≤0.35dB (0.15dB typical) and return loss exceeding 20dB. Testing conducted to ANSI/TIA/EIA-455-171-A-2001 standards ensures consistent, reliable performance. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm make this cable suitable for both traditional and modern wavelength-division multiplexing (WDM) systems. **Building Code & Compliance** The OFNR (Optical Fiber Non-conductive Riser) jacket rating ensures compliance with National Electrical Code (NEC) requirements for vertical runs between floors. RoHS and ELV compliant construction meets EU Directive 2002/95/EC standards. TAA certification qualifies this cable for U.S. government purchasing contracts, making it ideal for federal, state, and defense applications. **Professional Features** The bright yellow jacket provides exceptional visibility during installation and maintenance, reducing installation errors and expediting troubleshooting. The 1.8mm outside diameter delivers flexibility without compromising signal integrity. FC/APC connectors feature angled polishing for superior return loss performance and reduced back-reflection interference. **Practical Advantages** Available in custom lengths from 1m to 100m, this cable adapts to any network topology. Ships from strategically located U.S. warehouses in California, Texas, and South Carolina, ensuring rapid delivery. Qualified for free standard shipping on orders exceeding $99. The 90-day limited warranty provides peace of mind for critical installations. **Applications** Perfect for telecommunications networks, fiber-to-the-home (FTTH) deployments, data centers, campus networks, and research institutions requiring single-mode fiber connectivity with military-grade specifications.
