General Description
The Broadcom BCM957414M4142C is a dual-port 25 Gb/s
PCI Express 3.0 x8 Mezzanine Card designed to the Open
Compute Project (OCP) Mezzanine Card 2.0 Design
Specification with an SFP28 network as a Type 1 adapter,
with the board outline adhering to a form factor called out in
v0.5 of the specification. The adapter supports SFP28/
SFP+ optical modules and copper direct-attach cables. The
card uses the Broadcom BCM57414 25GbE MAC controller
with an integrated dual-channel 25 GbE SFI transceiver.
