Arista CAB-Q-Q-100G-3M | 100G QSFP28 DAC Twinax Copper Cable, 3m, Passive

Q: What is the maximum distance supported by the CAB-Q-Q-100G-3M?
A: The CAB-Q-Q-100G-3M supports a cable length of 3 metres (9.84 ft), making it suited for in-rack or short adjacent-rack connections in data centre and enterprise deployments. For longer distances, active optical cables or optical transceivers would be required.

Q: Is this cable compatible with non-Arista switches and servers?
A: The cable is compliant with QSFP28 MSA SFF-8665 and IEEE 802.3 standards, which means it is designed to work with any equipment featuring QSFP28 ports. However, Arista specifically validates and supports it with their own QSFP28-enabled switches. Always verify compatibility with your specific third-party vendor before deployment.

Q: Does this DAC cable require any software or drivers to operate?
A: No. The CAB-Q-Q-100G-3M is a passive plug-and-play cable that requires no additional drivers, firmware, or software configuration. Simply insert it into compatible QSFP28 ports and it will operate immediately.

Q: What is the power consumption of this cable?
A: The cable draws a maximum of 1.5W per end at 3.3V, making it one of the most power-efficient options for 100G interconnects compared to active optical modules. This is particularly beneficial in high-density data centre deployments with strict power budgets.

Q: Can I purchase this cable in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller with stock available for fast delivery across Australia. The CAB-Q-Q-100G-3M can be ordered online, and the team is available to assist with bulk orders or project-based requirements.

Q: What warranty does the Arista CAB-Q-Q-100G-3M include?
