The maximum power consumption of 400G OSFP and QSFP-DD transceivers depends on the type and specification of the products. However, some general comparisons can be made based on the following information:

OSFP allows higher power consumption of 12~15W, while the QSFP-DD allows lower power consumption of 7~12W.

The QSFP-DD ZR variant has a maximum power consumption of 12W.

The QSFP-DD ZR Plus variant has a maximum power consumption of 15W.

Coherent DWDM transceivers may draw up to as much as 24W per port.
