Add-On Q400G-4Q56G-PDAC1M-AO 400GbE Direct Attach Copper Cable

Overview

The Add-On Q400G-4Q56G-PDAC1M-AO is a 1-meter passive Direct Attach Copper (DAC) cable designed for high-density 400 Gigabit Ethernet (400GbE) network connections. It utilizes QSFP-DD connectors on both ends, enabling direct, short-reach interconnects between network switches, servers, or storage devices within a rack or between adjacent racks. This passive cable requires no external power, simplifying deployment and reducing potential points of failure in demanding data center environments.

Compatibility

This cable is engineered for compatibility with any network equipment featuring QSFP-DD (Quad Small Form-factor Pluggable Double Density) ports supporting 400GbE speeds. It is suitable for use with switches, NICs, and transceivers that adhere to the QSFP-DD MSA (Multi-Source Agreement) standards, ensuring broad interoperability across various manufacturers' hardware.

Installation Notes

The Q400G-4Q56G-PDAC1M-AO is a passive cable, meaning it draws power directly from the host equipment's QSFP-DD ports. Ensure the connected ports support 400GbE QSFP-DD connections. The cable's 1-meter length is ideal for intra-rack connectivity, minimizing cable clutter and signal degradation. For optimal performance, avoid sharp bends or excessive tension on the cable assembly.
