The JBX05206 represents a premium solution for organizations requiring reliable 40 Gigabit breakout connectivity in modern data center environments. As a direct compatible replacement for Cisco's QSFP-4X10G-AC2M, this 2-meter active DAC cable streamlines network provisioning while eliminating the need for separate transceivers and signal regeneration equipment. **Technical Excellence** This breakout cable utilizes active DAC technology to deliver exceptional performance across its 2-meter span. The 30AWG twinax copper construction provides optimal signal transmission with minimal attenuation, critical for maintaining 40GB/s throughput at full duplex. Compliance with IEEE 802.3ba standards guarantees interoperability with certified Cisco equipment and ensures future compatibility with emerging network infrastructures. **Versatile Configuration** The QSFP+ to 4x SFP+ configuration offers unmatched flexibility for network architects. By breaking out a single 40GB QSFP+ connection into four independent 10GB SFP+ channels, this cable enables diverse connectivity scenarios—from aggregated high-bandwidth trunk lines to granular multi-device connections. This versatility reduces equipment costs and simplifies network topology management. **Reliability & Compliance** RoHS, TUV, and UL certifications ensure compliance with international safety and environmental standards. The durable plastic jacketing protects the twinax conductor pair while maintaining flexibility for easy installation. Operating across 0-70°C temperature ranges, this cable performs consistently in standard and high-density rack environments. **Enterprise-Grade Support** Backed by a 90-day limited warranty and available custom brand programming options, the JBX05206 integrates seamlessly into existing procurement and asset management systems. Multiple shipping locations ensure rapid delivery, with free standard shipping on qualifying orders. **Ideal Applications** Perfect for data center upgrades, core network expansion, and high-performance computing clusters. Organizations transitioning from 10GbE to 40GbE infrastructure benefit from this cost-effective bridge technology. Service providers and enterprise IT teams appreciate the simplified deployment and reduced operational complexity compared to active transceiver solutions.
