Arista AOC-D-D-400G-15M | 400G QSFP-DD AOC, 8x 50G PAM-4, Multi-Mode, 15m

Q: What switching platforms is the AOC-D-D-400G-15M compatible with?
A: This AOC is designed for Arista QSFP-DD 400G platforms, including the 7060X4 Series and 7368X4 Series switches. It integrates natively with Arista EOS and CloudVision for seamless management.

Q: Can this cable be used with non-Arista equipment?
A: The AOC-D-D-400G-15M is QSFP-DD MSA compliant, meaning it should be compatible with third-party switches and routers that support the QSFP-DD 400G standard. However, Arista validates and supports it specifically within Arista EOS environments.

Q: Why choose an AOC over a DAC cable at 15 metres?
A: At 15 metres, active optical cables are the preferred choice as passive copper DAC cables are typically limited to 3–5 metres at 400G speeds. AOCs use optical fibre internally, offering greater reach, lower signal attenuation, lighter weight, and better bend radius for cable management in dense data centres.

Q: Does this cable support speeds lower than 400G?
A: Yes. In addition to 50Gb/s PAM-4 per lane (400G aggregate), the cable also supports 25Gb/s NRZ signals, making it suitable for mixed-generation environments where not all equipment has been upgraded to 400G.

Q: What warranty is included with the AOC-D-D-400G-15M?
A: Arista provides 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.
