Produktbeskrivning

The Broadcom BCM957508-N2100G is a dual-port 100 Gb/s PCI Express 4.0 x16 Network Adapter designed to the Open Compute Project (OCP) 3.0 Design Specification in small form factor with two QSFP56 network connectors. The adapter supports QSFP56/QSFP28/QSFP+ optical modules and copper direct-attach cables. The network adapter uses the Broadcom BCM57508 200GbE MAC controller with an integrated dual-channel 100GbE SFI transceiver.
