High-performance connectivity
Expand your connectivity options with the E25G30-F2 adapter, which supports
SR and LR transceivers, as well as DAC alternatives. Two 25GbE SFP28
ports effectively eliminate network bandwidth limitations, while backward
compatibility with 10GbE SFP+ equipment reduces implementation costs.
Benefit from a performance boost with CPU offloading technologies that
minimize network transfer overhead on the host system's processor.
