Q: What is the Arista CAB-Q-S-0.5M used for?
A: It is a breakout DAC cable that connects one 40G QSFP+ port on a switch or router to four independent 10G SFP+ ports on servers or other network devices. It is ideal for top-of-rack deployments and 40G-to-10G fan-out scenarios in data centres.

Q: Is this cable active or passive?

Q: Does this cable require separate transceivers?
A: No. The cable is pre-terminated with integrated QSFP+ and SFP+ connectors, so no additional transceivers are needed. Simply plug it directly into compatible ports.

A: The CAB-Q-S-0.5M is compatible with Arista switches featuring QSFP+ ports, such as the 7050, 7060, and 7260 series, as well as any third-party equipment conforming to QSFP+ MSA, SFF-8436, and SFF-8431 standards.
