Arista CAB-Q-Q-1M | 40GbE QSFP+ to QSFP+ Passive DAC Cable, 1 Metre

Q: What is the CAB-Q-Q-1M used for?
A: The CAB-Q-Q-1M is a 40GBASE-CR4 passive direct attach copper (DAC) cable designed for short-reach 40 Gb/s interconnects in data centre environments. It is ideal for top-of-rack switch-to-server connections or inter-switch links where distances of 1 metre or less are required.

Q: Is the CAB-Q-Q-1M compatible with my Arista switch?
A: Yes. The CAB-Q-Q-1M is natively supported across Arista's QSFP+ platforms including the 7050S, 7050T, 7050Q, 7050X, 7060CX, 7150S, 7250QX, 7260QX, 7260CX, 7280E, 7300X, 7320X, and 7500E series under all relevant Arista EOS releases.

Q: Does this cable require any special drivers or configuration?
A: No. The CAB-Q-Q-1M is a passive plug-and-play cable that is fully integrated with Arista EOS. It requires no drivers, SFP configuration, or third-party qualification — simply connect and it is recognised automatically by the platform.

Q: What is the difference between a passive DAC cable and an active optical cable?
A: A passive DAC cable like the CAB-Q-Q-1M uses copper Twinax wire with no active electronic components, making it extremely low cost, low latency, and low power. Active optical cables (AOC) use optical transceivers at each end and are suited to longer distances. For links of 1–3 metres, passive DAC cables are typically the most cost-effective choice.
