Frequently Asked Questions
Can it run at 10G?
Many SFP28 ports can be set to 10G, and the cable will follow the port speed, but this depends on the switch and NIC. If both ends are 10G-only SFP+ ports, use a 10G SFP+ DAC instead.
DAC or AOC: which should I use?
For runs of a few meters a passive DAC is the cheapest, lowest-power option. Active optical cables (AOCs) are lighter and reach farther, which suits longer runs between racks.
Compatible cable or genuine Dell: what is the difference?
This is a new third-party cable programmed (coded) to be recognized by Dell equipment that calls for this part number, at a fraction of the Dell-branded price. Choose the genuine Dell part only if your support contract or internal policy requires Dell-branded parts.
What warranty and shipping come with it?
Resilient Tec's lifetime warranty. US standard shipping is free with no minimum, and orders typically arrive in 3 to 5 days.
