Dual-Port 25GbE Adapter E25G21-F2
High-performance connectivity upgrade
The E25G21-F2 adapter gives you more connectivity options with support for SR and LR transceivers and DAC options. Dual 25GbE SFP28 ports help remove network bandwidth limitations, while backwards compatibility with 10GbE SFP+ equipment reduces installation and implementation costs. CPU offloading technologies reduce network transfer overhead on the host system's processor to boost system performance.
