In some scenarios, since the previous device port is still the original old-fashioned interface, a converter will be used to meet the application of the new port.

    For example, the previous CFP and CFP2 will use the CFP/CFP2 TO QSFP28 adapter module in order to adapt to the current mainstream QSFP28 interface.
