Arista AOC-Q-Q-40G-20M | 40GbE QSFP+ AOC, 20M, 4x 10G Lanes, Multimode Fibre

Q: Which Arista switches is the AOC-Q-Q-40G-20M compatible with?
A: The AOC-Q-Q-40G-20M is validated for use with Arista 7150S, 7250QX, 7280E, 7300X, 7320X, 7500E, and 7500R series switches. It is factory programmed for plug-and-play compatibility within the Arista ecosystem.

Q: What fibre type is required to use this AOC?
A: This cable is a complete assembly with integrated multimode fibre — no external fibre patch is required. It is a self-contained active optical cable that plugs directly into QSFP+ ports on both ends.

Q: How does an Active Optical Cable differ from a DAC or standard fibre transceiver?
A: An AOC integrates optical transceivers directly into the cable assembly, combining the benefits of fibre (low weight, longer reach, EMI immunity) with the simplicity of a direct-attach cable. Unlike DAC cables, AOCs can span up to 100 metres. Unlike discrete transceivers, no separate fibre patch cable is needed.

Q: What is the maximum supported distance for the AOC-Q-Q-40G-20M?
A: This cable supports a fixed cable length of 20 metres. If you require a different length — for example, 5M, 10M, or 30M — other SKUs in the Arista AOC-Q-Q-40G series are available. Contact IP Trading for guidance on the correct length for your installation.

Q: Can I purchase the AOC-Q-Q-40G-20M in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) supplies Arista networking products across Australia with fast shipping and expert B2B support. Contact our team for volume pricing, availability, and deployment advice.

Q: Is the AOC-Q-Q-40G-20M suitable for HPC and data centre fabric deployments?
A: Yes. The cable is designed specifically for high-performance computing and data centre environments, supporting both Ethernet and InfiniBand electrical compliance. Its lightweight design and low power draw (~1.4W) make it ideal for high-density spine-leaf and top-of-rack interconnects.
