The JBX83319 40-meter LC/ST OM2 50/125 multimode fiber patch cable represents a professional-grade solution for connecting network equipment in data centers, telecommunications facilities, and enterprise installations. Built with precision-engineered bend-insensitive fiber and durable OFNP jacketing, this cable delivers exceptional reliability and performance in demanding environments. **Key Features:** This duplex multimode cable features LC/UPC to ST/UPC connectors configured in Type A to B crossover polarity—the most common configuration for duplex patch cords. The bend-insensitive design allows installation around tight corners and equipment racks without compromising signal quality. With an outside diameter of just 1.8mm, the cable remains compact while maintaining robust construction. **Performance Specifications:** Optical performance is verified through ANSI/TIA/EIA-455-171-A-2001 standards testing. The cable achieves insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥60dB, ensuring superior signal integrity. Attenuation specifications include 3.5 dB/km at 850nm and 1.0 dB/km at 1300nm—ideal for multimode applications across both wavelengths. **Compliance & Standards:** TAA-compliant for government procurement requirements, this cable meets RoHS/ELV directives (EU directive 2002/95/EC) and is manufactured to the highest quality standards. Materials include plastic accessories and bend-insensitive fiber construction. **Practical Applications:** Perfect for network backbone connections, server-to-switch runs, and equipment interconnections in fiber-optic installations. The 40-meter length accommodates mid-range distances while remaining practical for most data center layouts. **Customization & Support:** Available in custom lengths to match specific installation requirements. Ships from multiple US distribution centers ensuring quick delivery. Free standard shipping applies to orders over $99. Each cable includes a 90-day limited warranty. **Care Notes:** Maintain proper cable management to maximize the bend-insensitive fiber benefits. Avoid sharp kinks and excessive pulling during installation. Keep connector caps installed when not in use to prevent dust contamination.
