Arista AOC-D-D-400G-20M | 400G QSFP-DD AOC, 20m, 8x 50G PAM-4, OM4 Multimode

Q: What platforms is the AOC-D-D-400G-20M compatible with?
A: This AOC is compatible with Arista 400G QSFP-DD switching platforms including the 7060X4, 7050X4, 7368X4, and 7358X4 series. Consult the Arista Transceiver and Cable Guide for the full list of supported platforms.

Q: What fibre type and reach does this cable support?
A: The AOC-D-D-400G-20M uses OM4 multimode fibre and supports a reach of 20 metres, making it ideal for intra-rack and top-of-rack to aggregation switch connections within data centre environments.

Q: Does this cable require any configuration or drivers to operate?
A: No. The AOC-D-D-400G-20M is a plug-and-play active optical cable. When used with compatible Arista platforms running EOS, it is automatically recognised with no additional configuration required.

Q: How does an Active Optical Cable differ from a DAC cable?
A: Unlike Direct Attach Copper (DAC) cables, active optical cables use fibre optics with integrated active electrical components at each end. This allows longer reach, lower signal loss, and reduced weight — advantages that become significant in high-density, high-bandwidth data centre deployments at 400G speeds.

Q: What warranty is included with this product?
A: The AOC-D-D-400G-20M includes a 1-Year Limited Hardware Warranty covering parts, repair, or replacement with a 10 business day turnaround. Optional Next Business Day and 4-hour advance hardware replacement support services are also available.
