The JBX83499 40m LC/LC OM2 50/125 multimode fiber patch cable represents the ideal solution for professional network environments requiring robust, standards-compliant fiber optic connectivity. This duplex patch cable is specifically engineered to meet the demanding requirements of modern data center infrastructures and enterprise-level telecommunications networks. **Key Technical Specifications:** Built with OM2 50/125 multimode fiber core, this cable delivers attenuation rates of 3.5 dB/km at 850nm or 1.0 dB/km at 1300nm, ensuring minimal signal loss over extended distances. The cable features LC/UPC to LC/UPC connectors with Type A to B crossover polarity—the most common configuration for duplex patch cords. With insertion loss maintained at ≤0.35dB (0.15dB typical) and return loss exceeding 60dB, signal integrity is guaranteed for critical applications. **Superior Design Features:** The bend-insensitive fiber technology combined with OFNP jacketing allows for flexible routing through tight conduit spaces without compromising performance. The slim 1.8mm outside diameter facilitates easier cable management in densely populated patch panel environments. Construction from TW, US, and CN manufacturing facilities ensures quality consistency across production batches. **Compliance & Standards:** Fully TAA compliant with RoHS/ELV certification under EU directive 2002/95/EC, this cable meets regulatory requirements for government and enterprise procurement. Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing performance reliability. **Practical Applications:** Ideal for connecting network switches, routers, and fiber-enabled network interface cards in data centers, telecommunications facilities, and enterprise network backbone infrastructure. The 40-meter length accommodates medium-distance runs while maintaining optical performance standards. **Value Proposition:** Backed by a 90-day limited warranty and available for custom lengths upon request, this cable represents an investment in network reliability. Free standard shipping on orders exceeding $99 with multiple distribution points across the US (Danville CA, Fort Worth TX, Beaufort SC) ensures rapid delivery and reduced shipping costs.
