Q: What is the maximum distance supported by the Arista CAB-Q-Q-2M?
A: The CAB-Q-Q-2M supports a maximum cable length of 2 metres. As a passive copper DAC cable, it is designed for short-distance interconnects — typically within a single rack or between directly adjacent racks in a data centre.

Q: Is the CAB-Q-Q-2M compatible with non-Arista switches?
A: The CAB-Q-Q-2M is designed and certified for use with Arista QSFP+ ports across all supported EOS releases. Compatibility with third-party equipment is not guaranteed, as some vendors lock transceivers and DAC cables to their own firmware. For best results, use it within an Arista infrastructure.

Q: Does this DAC cable require any additional power supply or drivers?
A: No. The CAB-Q-Q-2M is a passive copper twinax cable with no active electronic components. It draws a maximum of 1.5W per end directly from the QSFP+ port — no external power, drivers, or configuration is needed.

Q: What networking standards does the CAB-Q-Q-2M comply with?
A: It complies with IEEE 802.3ba (40G Ethernet), QSFP+ MSA (SFF-8436), QDR InfiniBand, and RoHS environmental standards, ensuring broad interoperability and regulatory compliance.
