Cisco Meraki MA-CBL-40G-1M 40GbE QSFP Stacking Cable

The Cisco Meraki MA-CBL-40G-1M is a 1-meter QSFP+ stacking cable that delivers low-latency, 40 GbE direct-attach copper connectivity—far beyond traditional Gigabit connectivity—in Meraki switch stacks for high-speed interconnects. Designed for Cisco Meraki MS-series switches that support 40G stacking, the cable is plug-and-play, enabling rapid expansion of a switch fabric, easy replacement of older interconnects, and reliable backbone links for campus networks, data centers, and virtualization-heavy environments. Technical details include QSFP+ to QSFP+ connectors, Direct Attach Copper (DAC) cabling, a 1-meter length, and a 40 Gigabit Ethernet data rate, with twinax shielding that helps minimize crosstalk and maintain performance during stacking operations. Common applications cover switch stacking, high-bandwidth interconnects for link aggregation, data center fabric interconnects, and workload-intensive environments where predictable latency and enterprise-grade reliability are essential for continuous network operations.
