470-ABQB Dell Compatible, 100G QSFP28 to 4xSFP28 Passive Breakout DAC Cable - 1m
Warranty: Lifetime
Quick answer: The 470-ABQB Dell-compatible cable is a 1-meter passive breakout DAC that splits one 100G QSFP28 port into four 25G SFP28 connections, for linking a switch to four servers or 25G ports in the same rack. It is coded to work in Dell switches that call for 470-ABQB. Resilient Tec sells it new, with a lifetime warranty and free US shipping from Knoxville, TN.

Frequently Asked Questions
Does the switch port need to be configured?
Yes. Set the QSFP28 port to 4 x 25G breakout mode in the switch configuration; each SFP28 leg then appears as its own 25G interface.
Will the SFP28 ends work in 10G SFP+ ports?
Usually not. The four legs run at 25G, so the ports on that end need to support 25G (SFP28). For 10G servers, use a 40G QSFP+ to 4 x 10G SFP+ breakout instead.
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.
