Can Mikrotik SFP28 reach 25Gbit/s when block diagram shows 10Gbit/s [Fixed]

Thu Dec 23, 2021 12:20 pm

Dear all,

I might be interested in buying some XS+DA0001 25G SFP28.

Simple questions : when the block diagram of a switch shows speed limited to 10Gb/s and the 25G XS+DA0001 is supported, can the XS+DA0001 25G SFP28 go further and reach 25Gb/s. My understanding is that speed is limited to 10Gb/s of the block diagram. I could not find any relevant information about this issue, so I am asking publicly.

Please confirm.

Kind regards,
FF

When the block diagram shows 10Gb/s, the port is only SFP+, not SFP28.
AFAIK the only Mikrotik device with SFP28 is CCR2004, so you only could get 25G speed between two of them.

Many thanks.

So I wonder why most 10Gb/s switches show the SFP28 as "supported".
What is the interest if speed is limited to 10Gb/s?

It essentially is only a "new" DAC cable that supports the higher SFP28 speed on supported hardware, while also being usable with SFP and SFP+ hardware.
I think they will stop selling the old DAC cables soon.
