Hi Jack, Thanks for weighing in. Actually your answer doesn’t read as the same one that Mitch gave. Further clarification:

The 100-10 doesn’t have to be purely passive, a switch which converts 100 G QSFP28 to 10 GigE SFP+, if a current and supported product would be fine. > I would think your best bet is to get a fully QSFP28 switch which supports > both 100GbE and 4x10GbE on its ports, the latter requiring MTP->4xLC fiber > breakouts to connect to 10G SFP interfaces. > I would imagine (though no claims that my imagination aligns with reality) > that any switch with QSFP28 ports which advertise 4x25G breakout mode will > also support 4x10G. The former might be more obviously advertised. So after a bit of googling I find that 25 GigE uses the SFP28 connector, which is pin and electrically compatible (though faster) than SFP+. So I suspect you’re correct here. This could be the solution we seek…. Jonathan -- You received this message because you are subscribed to the Google Groups "casper@lists.berkeley.edu" group.
