40G over 4xSFP+

Hi all,

I have multiple honeycomb lx-2s and would like to connect them to 40Gbps QSFP+ ports on a (mikrotik) switch.

the wiki states the following:

“For SERDES SD1 config 20 which is dual 40G, then dpmac.1 and dpmac.2 are to be used where dpmac.1 is achieved directly by using the QSFP port and dpmac.2 by using an 40G to 4x10G splitter cable where the splitter cable is connected to HoneyComb.“

If one uses this configuration, how does one need to plug in the (numbered) SFP+ cables of the breakout cable into the four ports of the honeycomb so one can use dpmac.2 as a qsfp+ nic?

Thanks,

Raphael
