Arista CAB-SFP-SFP-2-5M-Arista | 10G SFP+ Passive Twinax DAC Cable, 2.5m

Q: What is the maximum transmission distance for this cable?
A: The CAB-SFP-SFP-2-5M supports a maximum reach of 2.5 meters. For longer distances, consider fiber optic transceivers or active optical cables (AOC).

Q: Is this cable compatible with other vendor equipment?
A: Yes, as a passive copper DAC cable compliant with SFP+ MSA standards, it is designed to work with any SFP+ port supporting 10G connectivity, including equipment from Cisco, Juniper, Dell, and other manufacturers, provided the ports support passive copper cables.

Q: What are the advantages of DAC cables over fiber optic transceivers?
A: DAC cables offer lower cost, lower power consumption (no active electronics required), higher durability, lower latency, and simpler installation for short-reach connections within and between racks in data centers.

Q: Does this cable require any software licensing or configuration?
A: No, this is a passive copper cable that requires no licensing or special configuration. It is hot-pluggable and works immediately when connected between compatible SFP+ ports configured for 10G operation.

Q: Can this cable support speeds other than 10G?
A: While primarily designed for 10 Gigabit Ethernet, the cable also supports 8G Fibre Channel and InfiniBand QDR/DDR/SDR applications. Speed support depends on the host equipment capabilities.
