SFP28 optical transceiver modules
SFP28 ports are 25G speed ports and similar in size to a 10G SFP+ or 1G SFP port. They have supporting
circuitry to enable 25G speed transceiver, DAC, and AOC components.
Although 10G and 1G transceiver products may 'fit' into an SFP28 port, the particular switch model or
module may be limited in supporting lower speeds.
See Chapter 1, "Overview" for information regarding the type of connectors used by SFP28 port products.
Always refer to the Datasheet or QuickSpecs for the Switch product to see the current list of supported
transceivers.
