Add-On CAB-D-D-400G-1M-AO 400GbE Direct Attach Copper Cable

Overview

The Add-On CAB-D-D-400G-1M-AO is a 1-meter Direct Attach Copper (DAC) cable designed for high-speed 400 Gigabit Ethernet (400GbE) network connections. This cable is critical for building dense, high-performance data center fabrics and interconnecting network devices like switches and servers where maximum bandwidth is required over short distances. Its passive design means no power is required, simplifying deployment and reducing potential points of failure.

Compatibility

This 400GbE DAC cable is engineered for compatibility with network equipment supporting QSFP-DD (Quad Small Form-factor Pluggable Double Density) interfaces. It is suitable for connecting devices from manufacturers such as Arista, Cisco, Juniper, and others that utilize the QSFP-DD form factor for 400GbE aggregation and spine-leaf architectures. Always verify your specific network device's QSFP-DD port specifications against the 400GbE standard.

Installation Notes

Ensure the QSFP-DD ports on both the source and destination devices are clean and free of debris before insertion. The cable's pull tabs should be used for safe removal to prevent damage to the transceivers or ports. The 1-meter length is ideal for in-rack or adjacent-rack connections, minimizing signal degradation inherent in longer passive copper runs.
