No, the breakout end of this cable is designed for SFP56 packaging, which is smaller in size compared to QSFP28. Therefore, it is not compatible with a 50G QSFP28 port.

It is mainly used for short-distance interconnection (within 3 meters) between data center 50G SFP56 network cards and 200G switches.

Lower cost: DAC cable price is much lower than the same rate optical module; lower power consumption: no laser, energy consumption is close to zero; simpler deployment: no need for fiber cleaning, debugging, maintenance; lower latency: the physical layer is directly connected, there is almost no signal conversion delay.

I asked the customer services and they not sure about 2x112G Lane can be connected with 4x50G SPF56, but they can provide 200G QSFP56 transceivers. I buy two of them for the test and it's pretty good.
