The JBX43665 3-meter LC/UPC to FC/APC simplex singlemode fiber patch cable represents premium connectivity for professional network infrastructure. This carefully engineered cable is specifically designed to meet the rigorous demands of telecommunications companies, data centers, and enterprise networking environments requiring reliable fiber optic signal transmission. **Technical Excellence** Features a standard 9/125 singlemode core with G.657.A1 specification glass fiber, ensuring optimal performance across critical wavelengths. The cable achieves exceptional insertion loss ratings of ≤0.35dB (0.15dB typical) and return loss ≥20dB, tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm demonstrate the cable's suitability for long-distance signal transmission. **Durability and Compliance** The 1.8mm outside diameter jacketing is OFNR (Optical Fiber Nonconductive Riser) rated, providing safety compliance for vertical runs in building plenums. RoHS and ELV compliant construction ensures environmental responsibility. TAA compliance makes this cable eligible for government and institutional procurement. Yellow jacket color aids in quick identification within complex cable management systems. **Flexible Configuration** While this product comes pre-manufactured at 3 meters, custom lengths are available to match your specific installation requirements. The simplex design is ideal for unidirectional signal transmission applications. Straight-through polarity ensures proper signal flow from source to destination. **Practical Advantages** With free standard shipping on orders over $99 and a 90-day limited warranty, this cable offers excellent value. Available from multiple distribution centers (Danville, CA; Fort Worth, TX; Beaufort, SC) for faster delivery. The cable's specifications make it suitable for LAN/WAN interconnections, equipment interfacing, and signal transmission in professional network environments where quality and reliability are paramount. **Compatibility** Perfect for connecting LC/UPC-equipped devices to FC/APC termination points, this cable bridges connector type differences while maintaining superior signal integrity. Whether upgrading legacy systems or expanding modern infrastructure, this patch cable provides the performance and reliability network professionals demand.
