Add-On CAB-D-D-400G-2M-AO 400GbE Direct Attach Copper Cable

Overview

The Add-On CAB-D-D-400G-2M-AO is a 2-meter Direct Attach Copper (DAC) cable designed for high-speed 400 Gigabit Ethernet (400GbE) network connections. This cable is engineered for short-reach applications within data centers, server racks, and high-performance computing environments where reliable, low-latency data transfer is critical. Its passive design means no power is required, simplifying deployment and reducing potential points of failure. The CAB-D-D-400G-2M-AO model specifically addresses the need for a robust, cost-effective interconnect for 400GbE infrastructure.

Compatibility

This 400GbE DAC cable is designed to be compatible with network devices featuring QSFP-DD ports. It is intended for use with Arista 400GbE switches and transceivers, as well as other networking equipment that supports the QSFP-DD form factor for 400GbE connectivity. Ensure your network hardware utilizes QSFP-DD ports for successful integration.

Installation Notes

The CAB-D-D-400G-2M-AO cable features integrated QSFP-DD connectors that snap securely into place. For optimal performance and to prevent signal degradation, ensure the cable is routed without sharp bends or excessive tension. The passive nature of this DAC cable means no software configuration is required on the connected devices; simply plug and play.
