Introduction
The ML4062-MCB-MXP-ETH is designed to provide an efficient and easy method of
programming and testing 400G QSFP-DD transceivers and active optical cables. It includes a
complete user-friendly GUI supporting all features defined by QSFP-DD MSA and simplifying
configuration processes to enable intuitive memory map programming and testing. It is
designed to simulate an ideal environment for QSFP-DD transceivers module testing,
characterization and manufacturing.
