Single-Port 100 Gb/s QSFP56 Adapter

The Broadcom BCM957504-N1100G is a single-port 100 Gb/s QSFP56 Ethernet adapter built on the OCP 3.0 form factor. It targets enterprise and cloud-scale servers that need line-rate, full-duplex throughput at 100, 50, 40, 25 or 10 Gb/s for high-performance computing, storage disaggregation and machine-learning workloads.

Halogen-Free OCP 3.0 Card With Pull-Tab

The halogen-free PCB meets OCP 3.0 mechanical and thermal specifications and includes a pull-tab for tool-less insertion and removal from compatible server cages. A single QSFP56 cage accepts direct-attach copper or optical transceivers, while the PCIe 4.0 x16 edge connector supplies the bus bandwidth required for sustained 100 Gb/s operation.

Verify OCP 3.0 Slot And PCIe 4.0 x16 Wiring

Before ordering, confirm the server provides an OCP 3.0 mezzanine slot wired for PCIe 4.0 x16 electricals; lesser lane counts will reduce available throughput. Ensure the chassis airflow and power budget match the adapter’s requirements and that a suitable QSFP56 module or cable is available for the intended link distance.

Questions about this item

What does the PCIe 4.0 x16 interface cap at for this BCM957504-N1100G?

The PCIe 4.0 x16 slot delivers the bandwidth needed for the single 100 Gb/s QSFP56 port to run at line-rate, full-duplex throughput.

What physical slot and form factor does the BCM957504-N1100G need to mount?

It installs in an OCP 3.0 mezzanine slot with a pull-tab and uses a single QSFP56 cage for the 100/50/40/25/10G transceiver.

How is the BCM957504-N1100G installed, and which step is often missed?

Insert the card into the OCP 3.0 bay until the pull-tab clicks, secure the retention screw, then seat a compatible QSFP56 module — skipping the screw leaves the adapter loose and breaks link.
