The NVIDIA MAM1Q00A-QSA28 is a DynamiX QSA28 port adapter that converts a QSFP28 cage into an SFP28 port. It lets a 100G QSFP28 switch or adapter port accept an SFP28 transceiver or cable, so a high-density port can serve a lower-rate endpoint without changing the platform or re-cabling the rack. The MAM1Q00A-QSA28 runs from a 3.3V supply, dissipates 0.1W, and is rated for 0C to +70C. It is supplied in tray packaging under the Mellanox brand within NVIDIA networking.
QSA adapters are used in datacenter and HPC fabrics when a 100G-capable switch or NIC port has to connect to a 25G endpoint: linking top-of-rack QSFP28 ports to SFP28 server NICs, reusing existing SFP28 optics and DACs during a fabric upgrade, and preserving port flexibility on switches that would otherwise need a breakout cable. Buyers are typically datacenter network engineers, HPC and AI cluster build teams, and integrators specifying NVIDIA/Mellanox networking hardware.
