Produktbeskrivning
The Broadcom BCM957412N4120C is a dual-port 10 Gb/s PCI Express 3.0 x8 network adapter designed to the Open Compute Project (OCP) 3.0 Design Specification in small form factor with two SFP+ network connectors. The adapter supports SFP+ optical modules and copper direct attach cables. The network adapter uses the Broadcom BCM57412 25GbE MAC controller with an integrated dual-channel 10GbE SFI transceiver.
