2m (7ft) Cisco QSFP-4SFP25G-CU2M Compatible 100G QSFP28 to 4x25G SFP28 Passive Direct Attach Copper Breakout Cable
We have a Dell S5224F Switch and I need to make use of the 100GB ports as the switch is full. Would this cable: FS P/N: Q-4S28PC05 work with a 10GB NIC? FS P/N: X710BM2-F2. Or only with 25GB Nic’s?

Upon confirmation, your device supports 100G and also supports branching applications. Your device can also be used with a 25G NIC #75603, but not with a 10G NIC. The customized item #49617 is recommended and select "Dual Compatibility Solutions" in the compatibility options. Choose Dell compatibility for the 100G port and Cisco compatibility for the 25G port.

Can 100G breakout DAC be used for 40G Switch?
by J***s on 10/13/2021
Generally speaking, QSFP28 cable can be used for 40G, and the transmission rate is 40G. Some switches recognize it automatically, others require a command to slow down the port before it can be recognized.

I need to split QSFP28 into 4x25G SFP28. Should I use 100G to 4X25G DAC or 100G to 4X25G AOC?
by E***d on 10/10/2021
The 100G to 4x25G DAC is recommended for short-distance transmission within 5m, which helps you save the cost, for the transmission distance longer than 5m, you can choose the 100G to 4x25G AOC to ensure stable transmission.

What does breakout mode of QSFP28 cable mean?
by M***n on 09/02/2021
Breakout mode refers to running a 100G port as 4 separate channels of 25G. When breaking out a single 100G port to 4x 25G , Forward Error Correction (FEC) mode on both ends of the link must be the same to ensure link-up.
