In Praise of the QSFP – from 40GbE to 400GbE and Beyond

Cisco is building and testing QSFP-DD systems and modules capable of driving 400GbE Ethernet electrical interfaces and cooling 20W modules with margin to address thermal and high-speed electrical challenges. These advances for the 400GbE are not at the limits of what is possible. Further innovation will reduce power as chips move to 7nm from the current 16nm processes.
