Add-On QDD-400-CU1M-AO 400GbE Direct Attach Cable

Overview

The Add-On QDD-400-CU1M-AO is a 1-meter Direct Attach Copper (DAC) cable designed for 400 Gigabit Ethernet (400GbE) connections. This cable is critical for high-density data center environments where short-reach, high-speed interconnectivity between network devices is paramount. It provides a cost-effective and power-efficient solution for linking switches, routers, and servers within a rack or between adjacent racks, ensuring maximum data throughput without the need for transceivers.

Compatibility

This 400GbE DAC cable is engineered to be compatible with Cisco QSFP-DD (Quad Small Form-factor Pluggable Double Density) ports. It is suitable for use with Cisco Nexus 9000 series switches and other network equipment featuring QSFP-DD 400G ports that support direct attach copper cabling. Always verify your specific equipment's QSFP-DD port compatibility for DAC cables.

Installation Notes

The QDD-400-CU1M-AO features integrated QSFP-DD connectors that plug directly into the host equipment's ports. Ensure the locking tabs on the connectors are fully engaged to secure the cable. For optimal performance and to prevent signal degradation, avoid sharp bends or excessive tension on the cable. The cable's 1-meter length is ideal for intra-rack connections, minimizing cable clutter and signal path length.
