Dual-Port 10GBASE-T Adapter

The Broadcom BCM957416N4160C is a dual-port 10GBASE-T network adapter built to the OCP 3.0 small-form-factor specification. It connects through a PCI Express 3.0 x8 interface and uses the Broadcom BCM57416 controller. The card supports 10GBASE-T and 1000BASE-T Ethernet on Category 6, 6A, or 7 twisted-pair cables, with 1000BASE-T also operating on standard Category 5e UTP.

Suited For Virtualised And High-Throughput Servers

This adapter suits servers that need two 10 Gb/s copper links with SR-IOV virtualization, supporting up to 128 virtual functions, and hardware offloads for tunnelling protocols such as VXLAN, NVGRE, and Geneve. It also provides RDMA over Converged Ethernet and DCB features including PFC, ETS, QCN, and DCBx. Buyers who require fibre connectivity, a single-port design, or a lower-speed 1 Gb/s-only card should consider other options.

Deciding Specification: PCI Express 3.0 x8 Interface

The card requires a PCI Express 3.0 x8 slot to operate at its rated 10 Gb/s per port. If the host system only offers x4 or PCIe 2.0 lanes, throughput will be limited and the adapter may not function as intended. Verify that the server or workstation provides a compatible x8 slot before purchase.

Questions about this item

Is the BCM957416N4160C available in a single-port version or only as the dual-port model shown?

The BCM957416N4160C is supplied as a dual-port 10GBASE-T adapter; other port counts would carry different part numbers.

What does the 10 Gb/s rating mean when the card is installed in a server?

Each port can negotiate 10GBASE-T or 1000BASE-T on Category 6, 6A or 7 cabling, with Energy Efficient Ethernet active on both speeds.

The card uses a PCIe 3.0 x8 interface — what does that cap in practice?

The x8 PCIe 3.0 link provides the electrical bandwidth for two 10 Gb/s ports plus SR-IOV with up to 128 virtual functions and RoCE offloads.
