Can 200G QSFP56 products be used with a 400G QSFP-DD port?

In general, 400G QSFP-DD ports are backward compatible with QSFP56, so they can be used together.

Can a DAC cable be provided for a transmission distance of 5m?

The maximum transmission distance for a 200G DAC cable is 3m. For distances exceeding 3m, it is recommended to choose AOC (Active Optical Cable) or utilize modules and fiber patch cords.
