ML4046 (Loopback module) is used for testing uQSFP transceiver ports under board level tests. Substituting a full-featured uQSFP transceiver with the ML4046 provides a cost effective low loss method for uQSFP port testing via electrical loopback. It can emulate power classes from 1 to 7 using a +3.3V voltage supply.

ML4044 (MCB) is designed to provide an efficient and easy method for programming and testing 100G uQSFP transceivers and active optical cables. It includes a complete user-friendly GUI supporting all features defined by uQSFP MSA. This simplifies configuration processes to enable intuitive memory map programming and testing..

ML4045 (Breakout module) can be used for testing and characterizing 4x28G line cards and host interfaces.
