Adapt a 100G QSFP28 interface to 25G SFP28 connectivity where a network design calls for those two interface formats. Axiom Memory AXG105118 is an adapter module specified with a 100G QSFP28 side and a 25G SFP28 side. It provides a defined interface transition rather than a separate switching or routing function. Use the module where 25G SFP28 connectivity must be accommodated at a 100G QSFP28 interface. The adapter format keeps the interface relationship explicit: QSFP28 is the 100G side and SFP28 is the 25G side. That distinction helps engineers match the required interface format when documenting network ports and selecting the associated connection components. This version carries both a TAA designation and an industrial-temperature designation. Those characteristics distinguish it for installations where those requirements are part of the hardware selection criteria. Its purpose remains focused on bridging the stated QSFP28 and SFP28 interface formats, making it appropriate for network hardware designs that need this specific 100G-to-25G adapter arrangement.
