Single-port 100Gbps OCP 2.0 adapter

The Broadcom BCM957504-M1100G16 is a new single-port network adapter delivering 100Gbps Ethernet over a PCI Express 3.0 x16 interface. It follows the OCP Mezzanine 2.0 Type 2 specification with v0.5 board dimensions and uses the BCM57504 controller with an integrated 100GbE SFI transceiver.

QSFP56 media flexibility and BroadSAFE security

The card provides a pluggable media interface accepting QSFP56, QSFP28 or QSFP+ optical transceivers as well as copper direct-attach cables. It supports 50G PAM-4 and 25G NRZ signalling and is fully compliant with the SFF-8402 standard. Broadcom BroadSAFE technology delivers the industry's most secure PCIe adapter solution.

Suited for OCP mezzanine slots needing 100GbE

This adapter fits servers and appliances with an OCP 2.0 mezzanine slot that require a single 100GbE port and SR-IOV with up to 1k virtual functions. It is not for systems lacking an OCP mezzanine connector or for deployments needing multiple ports on a single card.

Questions about this item

Will I need to replace the optical transceiver as speeds or standards change?

The card uses a QSFP56/QSFP28/QSFP+ interface so you can swap the transceiver or direct-attach cable when requirements change.

Does the PCIe 3.0 x16 link become the bottleneck at 100 Gb/s line rate?

PCIe 3.0 x16 provides enough raw bandwidth for the single 100 Gb/s Ethernet port to run at line rate.

How much heat or noise does the adapter add when it runs continuously?

The mezzanine card has no onboard fan; thermal performance depends on the host server's airflow design.
