nVidia Mellanox MAM1Q00A-QSA28 100GB QSFP28 to 25GB SFP28 Ethernet Adapter

The nVidia Mellanox MAM1Q00A-QSA28 is a QSFP28 to SFP28 adapter designed by NVIDIA. It features a compact transceiver form factor and supports transmission from 100 GbE (QSFP28) down to 25 GbE (SFP28), enabling connectivity between differing port formats.

This single-port passive converter allows the use of lower data rate SFP28 cables in higher-speed QSFP28 ports, maintaining physical compatibility across Ethernet switch or network interface platforms. No external power source is required as it operates passively within compatible hardware slots.
