Single-Port 200 Gb/s OCP 3.0 Adapter

The Broadcom BCM957508-N1200G is a single-port network adapter delivering 200 Gb/s throughput over a QSFP56 connector. It plugs into a PCIe 4.0 x16 slot and conforms to the OCP 3.0 small-form-factor specification. The card supports link speeds of 200, 100, 50, 40, 25 and 10 GbE with compatible optics or copper cables.

Suitable For High-Density Server Deployments

This adapter suits data-centre operators who need line-rate 200 Gb/s connectivity in an OCP 3.0 chassis and value features such as NIC partitioning with 16 physical functions and the TruFlow engine for vSwitch acceleration. It is not for workstations or desktop PCs that lack an OCP 3.0 mezzanine slot, nor for environments limited to PCIe 3.0 where the x16 bandwidth cannot be fully utilised.

PCIe 4.0 x16 Interface Determines Compatibility

The adapter requires a PCI Express 4.0 x16 electrical connection to achieve its rated 200 Gb/s line rate. Verify that the host platform provides an OCP 3.0 SFF slot wired for PCIe 4.0 x16 before purchase; a narrower or older-generation link will restrict throughput.

Questions about this item

How do I install the BCM957508-N1200G into an OCP 3.0 slot and what PCIe link width must the server provide?

Insert the OCP 3.0 SFF adapter into a compliant cage until it latches, then verify the host negotiates a PCIe 4.0 x16 link so the 200 Gb/s port can run at line rate.

Which replaceable media does the QSFP56 port accept for future upgrades or repairs?

The cage takes QSFP56, QSFP28 or QSFP+ transceivers and direct-attach cables, so you can swap optics or copper leads without replacing the adapter.

At what throughput does the BCM57508 controller hit its first sustained-use bottleneck?

The single 200 Gb/s lane is the limiting factor; once aggregate traffic reaches 200 Gb/s full duplex the adapter cannot push more data without dropping frames.
