FAQs

Q: What is the maximum reach of the CAB-SFP-SFP-2M cable?
A: This passive direct attach copper cable supports a maximum reach of 2 meters, making it ideal for short-distance connections within a rack or between adjacent racks in data centres.

Q: Is this cable compatible with non-Arista equipment?
A: Yes, the CAB-SFP-SFP-2M is MSA-compliant and can work with any equipment that supports standard 10G SFP+ DAC connections. However, it is specifically coded and tested for optimal compatibility with Arista switches and routers.

Q: What are the advantages of using a DAC cable over optical transceivers?
A: DAC cables offer several benefits including lower cost, lower power consumption, simpler installation without the need for separate transceivers and fibre cables, and reduced latency for short-reach applications.

Q: Can this cable support speeds lower than 10G?
A: While the cable is designed for 10GBASE-CU operation, compatibility with lower speeds depends on the connected equipment. Many 10G SFP+ ports can auto-negotiate to lower speeds if supported by the host platform.

Q: What is the warranty coverage for this Arista cable?
A: Arista cables typically come with standard coverage. Contact your authorised Arista reseller for specific warranty terms and support options.
