QSFP-DD Passive Loopback Module ML4062 is used for testing QSFP-DD transceiver ports under board level tests. By substituting a full-featured QSFP-DD transceiver with the ML4062, the electrical loopback will provide a cost effective low loss method for QSFP-DD port testing.
The ML4062 is packaged in a standard MSA housing that is compatible with all QSFP-DD ports. Transmitting data from the host is electrically routed (internal to the loopback module) to receive data outputs and send them back to the host. It provides an economical way to exercise QSFP-DD ports during R&D validation, production testing, and field testing.The ML4062 provides 9 power classes using a customer supplied +3.3V voltage supply .
ML4057 provides an easy and effective solution for programming and characterization of CFP8 modules. It includes a complete user friendly GUI supporting all features defined by CFP8 MSA . The latter simplifies the configuration process. Current sense circuit is also included on the Host for checking modules’ power class.
ML4058 breakout module can be used to test and to characterize line cards with 16x25G CFP8 host interfaces.
ML4059 is used for Testing CFP8 ports working at 16x25Gbps. It is packaged in MSA compliant housing offering excellent heat dissipation. The module can be programmed to different power levels through MDIO interface; thus, emulating all CFP8 power classes.
ML4046 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 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.
