25G SFP28 DACs are best suited for short-reach connections within the same rack or between adjacent racks. They offer lower cost, lower power consumption, and true plug-and-play deployment. When the link distance is within the supported range of the DAC (typically ≤5 m) and there is no high requirement for cabling flexibility, a DAC is a more economical and efficient choice. For longer distances, cross-row cabling, or applications requiring higher cable flexibility, optical transceivers with fiber are the preferred solution.

Hello, normally the #65844 could only be used on the 25G ports, thank you.
