Arista H-O400-4Q100-3M Overview
The H-O400-4Q100-3M is a high-performance direct attach copper breakout cable designed to bridge 400G QSFP-DD ports to four individual 100G QSFP28 interfaces. This robust interconnect solution is engineered for high-density data center environments where reliable, low-latency connectivity is essential for server-to-switch fabric expansion. By utilizing the H-O400-4Q100-3M, network administrators can effectively manage complex port configurations while maintaining signal integrity across the three-meter length. This cable assembly serves as a critical component for scaling bandwidth in demanding enterprise and cloud networking architectures.
Arista H-O400-4Q100-3M Technical Details
The H-O400-4Q100-3M features precision-engineered connectors that ensure a secure physical link between high-speed networking hardware and peripheral devices. Each unit is constructed with high-quality shielding to minimize electromagnetic interference, supporting consistent throughput during intensive data transmission cycles. Because this is a passive copper assembly, it offers an energy-efficient alternative to optical transceivers for short-reach rack-to-rack applications. Prospective buyers of used hardware will appreciate the durable jacket design and reliable latching mechanisms that maintain connection stability over extended periods of operation.
