Product Features
Technical Overview
This DAC cable adheres to the 40GBASE-CR4 and 10GBASE-CU standards, delivering a 40 Gbit/s aggregate data transfer rate through its QSFP+ interface, which breaks out into four independent 10 Gbit/s SFP+ channels. The twinaxial copper construction ensures signal integrity with low latency and minimal crosstalk, suitable for high-performance computing and storage networking.
The cable features a male QSFP+ connector on one end and four male SFP+ connectors on the other, all designed for hot-pluggable insertion into compatible network devices. Its passive design means it operates without signal retiming or amplification, relying on the host device's electrical specifications for optimal performance.

FAQ
What is the maximum data transfer rate of this cable?
This cable supports an aggregate data transfer rate of 40 Gbit/s through its QSFP+ interface, which breaks out into four independent 10 Gbit/s channels via the SFP+ connectors. It is designed for high-speed networking applications in data centers and enterprise environments.
How long is the cable and what type is it?
The cable is 7 meters long, equivalent to 23 feet. It is a twinaxial copper cable, which provides reliable electrical signaling for short-reach connections without the need for optical components, making it a cost-effective solution for distances up to 7 meters.
Is this cable compatible with Arista network devices?
Yes, this cable is Arista compatible, meaning it is designed to work seamlessly with Arista switches and other supported network equipment that use QSFP+ and SFP+ interfaces. It ensures reliable connectivity and performance in Arista-based network infrastructures.
What does 'passive DAC' mean for this cable?
Passive DAC stands for passive direct attach copper. It indicates that the cable operates without active electronic components for signal retiming or amplification, relying instead on the host device's electrical specifications. This results in lower power consumption, reduced heat generation, and a simpler, more reliable design compared to active cables.
