How Much Do You Know About the 200G QSFP56 Transceivers?

QSFP56 made the change from NRZ to PAM4 encoding. Though QSFP56 still uses 4 lanes like QSFP28, the modulation is doubled to 50G per channel which enables more data on existing fiber. Accordingly, it more suitable for hyper-scale data center networks.
