The Mellanox MMA2P00-AS is a genuine NVIDIA/Mellanox SFP28 optical transceiver module for 25GbE short-distance connections via multimode optical fiber. It operates at a nominal wavelength of 850 nm and supports data rates up to 25 Gbps, with a range of up to 100 m on OM4 MMF and 70 m on OM3 MMF at 25 Gb/s, and up to 100 m on OM3 at 10 Gb/s.

This hot-pluggable transceiver complies with IEEE 802.3bm, 10GBASE-SR/25GBASE-SR standards, and the SFP28 MSA. It includes digital diagnostic monitoring via I2C (temperature, voltage, optical power), configurable Tx/Rx re-timing, programmable equalization and emphasis controls, VCSEL transmitter, PIN photodiode receiver, and Class 1 laser safety.

The module uses a duplex LC/UPC optical connector, is powered by 3.3 V, and has low power consumption below 1 W. It is designed for reliable high-performance networks in data centers and Ethernet operational environments.
