Arista CAB-Q-Q-100G-1M QSFP28 100GbE 1m Passive DAC

The Arista CAB-Q-Q-100G-1M is a passive Direct Attach Cable (DAC) designed for high-density 100 Gigabit Ethernet interconnection in modern data center architectures. It terminates with QSFP28 connectors on both ends and spans 1 meter, enabling direct chip-to-chip communication without active signal conditioning. The cable delivers full 100GbE line-rate performance with minimal latency and power consumption, making it ideal for intra-rack and adjacent-rack connections in leaf-spine fabric topologies.

This Arista-branded passive DAC is engineered for seamless integration within Arista switch ecosystems, where it undergoes rigorous vendor validation to ensure compatibility with Arista's 7050, 7150, 7250, and 7350 series platforms. The passive architecture eliminates the operational complexity and heat generation associated with active optics, while maintaining signal integrity across the 1-meter distance through precision impedance matching and shielding.

Commonly deployed in financial services data centers, cloud service provider infrastructures, and large-scale enterprise campus networks, the CAB-Q-Q-100G-1M supports predictable, vendor-validated performance in production leaf-spine fabrics where uplink and east-west traffic demands justify 100GbE density.

Ideal for

• Leaf-to-spine fabric uplinks in multi-tier data center networks requiring 100GbE throughput
• High-performance computing clusters with tightly coupled node-to-switch connectivity
• Cloud provider POD-level interconnect within rack clusters
• Financial services data centers consolidating multiple trading and market-data workloads
• Adjacent-rack server-to-storage 100GbE direct connections with sub-microsecond latency
• Hyperscaler network fabric backbone where vendor-validated passive DACs reduce operational overhead
