The Extreme Networks compatible QSFP28 to SFP28 adapter converter module provides 25G Ethernet connectivity for QSFP28 100G ports. This module is compliant with QSFP28 MSA SFF-8665 and SFP28 MSA SFF-8432. The built-in MCU enables I2C reading of SFP28 registers by reading QSA registers. The high-speed data channel of the SFP28 receptacle is connected to lane 1 of the QSFP28 connector. The other three channels on the QSFP28 connector are not connected.
Note: The FS P/N is changed from CVR-QSFP28-SFP28 to QSFP28-SFP28-CVR, but the product is the same. Only the FS P/N has been changed.

I haven't had the chance to test the modules ones yet, but they appeared to have a connection when I plugged it in so it’s all looking good thanks!
