The JBX45149 40m OM3 SC/SC Multimode Fiber Patch Cable represents the ideal solution for enterprise-grade network connectivity. Built to ANSI/TIA/EIA-455-171-A standards, this duplex patch cord combines professional-grade performance with practical flexibility. **Technical Excellence:** FeaturingOM3 50/125 multimode fiber, this cable supports high-bandwidth applications including 10 Gigabit Ethernet over extended 40-meter runs. The bend-insensitive fiber technology allows for tighter routing through conduits and around equipment without signal degradation. Attenuation specifications of 3.5 dB/km at 850nm and 1.0 dB/km at 1300nm ensure consistent performance across multiple wavelengths. **Superior Connectivity:** The SC/UPC connectors provide reliable, repeatable connections with industry-leading return loss performance of ≥60dB. Low insertion loss (≤0.35dB typical) minimizes signal loss and reduces power budget requirements. Type A to B crossover polarity configuration is the most common standard for duplex patch cords. **Compliance & Durability:** Fully TAA compliant and RoHS/ELV certified, meeting strict government procurement and environmental standards. The OFNP-rated bend-insensitive jacket provides fire safety while withstanding rigorous installation conditions. 1.8mm outer diameter balances protection with space efficiency. **Practical Advantages:** Custom lengths available for specific deployment requirements. Free standard shipping on orders over $99. Multi-location warehousing ensures rapid delivery. 90-day limited warranty provides peace of mind. **Ideal Applications:** Data center interconnects, campus backbone networks, equipment-to-equipment connections, and high-speed LAN installations. Compatible with standard SC fiber optic equipment and infrastructure. Manufactured in Taiwan, the US, or China with consistent quality standards, this patch cable delivers enterprise reliability at competitive pricing.
