Produktbeskrivning
The Broadcom BCM957414M4143C is a single-port 50 Gb/s, PCI Express 3.0 x8 Mezzanine Card, designed to the Open Compute Project (OCP) Mezzanine Card 2.0 Design Specification with a QSFP28 network connector as a Type 1 adapter with the board outline adhering to the original v0.5 dimensions. The adapter supports both QSFP28 optical modules and copper direct-attach cables. The card uses the Broadcom BCM57414 50GbE MAC controller with an integrated single-channel 50GbE SFI transceiver.
