Supermicro compatible AOM-SFP28-25GBE-SR-1-MLN Description
EdgeOptic's AOM-SFP28-25GBE-SR-1-MLN compatible is a Supermicro-coded 25GBASE-SR SFP28 transceiver built on Mellanox EEPROM identification, matching the original Supermicro SKU used with ConnectX-4 Lx EN-based SFP28 ports. The MLN suffix denotes the Mellanox-coded variant and cross-references to the Mellanox MMA2P00-AS OEM part number. Supermicro also ships an INT-suffix variant with Intel EEPROM coding for Intel-based SFP28 adapters; the two are not interchangeable at the EEPROM level.
Optical specs: 850 nm VCSEL transmitter, PIN photodiode receiver, TX power -8.4 to +2.4 dBm, RX sensitivity better than -10.3 dBm, 5.3 dB link budget. Reach is 100 m on OM4, 100 m on OM5, and 70 m on OM3 with an LC/UPC duplex connector. The module is IEEE 802.3by Clause 112 compliant with RS-FEC via Clause 91 (RS(528,514)) when negotiated by the host port.
Electrical interface follows SFF-8431 and SFF-8432 for the SFP28 cage, with a supported data rate range of 8.5 to 28.1 Gbps covering 10GBASE-SR and 25GBASE-SR operation on dual-rate ConnectX-4 Lx EN ports. Digital diagnostics are SFF-8472 compliant and read back through mstflint, ethtool, and Supermicro IPMI. Power dissipation is 0.3 W and the module operates across 0-70 C.
Platform coverage includes Supermicro servers with onboard 25G SFP28 ports, Supermicro AOC-S25G-m2S and AOC-AH25G-M2S2TM-O add-on cards, and Supermicro AIOM 25 GbE modules built on Mellanox ConnectX-4 Lx EN silicon. Because the EEPROM identifies as Mellanox, the module is also accepted on native Mellanox ConnectX-4 Lx and SN-series switches requiring Mellanox-coded optics.

Frequently Asked Questions
Is the AOM-SFP28-25GBE-SR-1-MLN equivalent to the Mellanox MMA2P00-AS transceiver?
Functionally and optically they match: both are 25GBASE-SR SFP28 modules, 850 nm VCSEL, 100 m OM4. The MLN suffix on the Supermicro SKU indicates Mellanox EEPROM coding, which is the same vendor identification used by Mellanox's MMA2P00-AS. Supermicro sells the AOM-SFP28-25GBE-SR-1-MLN as the Supermicro-branded equivalent for ConnectX-4 Lx EN-based adapters.
What is the difference between the MLN and INT suffix variants of AOM-SFP28-25GBE-SR?
The optical transceiver is physically identical. The difference is the EEPROM coding: MLN = Mellanox-coded for ConnectX-4 Lx EN-based Supermicro adapters (AOC-S25G-m2S, AOC-AH25G-M2S2TM-O). INT = Intel-coded for Intel E810/XXV710-based Supermicro adapters. Select the variant that matches the NIC silicon in the target server.
Which Supermicro adapters and AIOM modules accept the AOM-SFP28-25GBE-SR-1-MLN?
Supermicro lists the AOM-SFP28-25GBE-SR-1-MLN for use with the AOC-S25G-m2S and AOC-AH25G-M2S2TM-O add-on cards, and Supermicro AIOM 25 GbE modules built on Mellanox ConnectX-4 Lx EN. It also operates in native Mellanox ConnectX-4 Lx NICs and compatible Mellanox SN-series switches because the EEPROM matches.
Does the AOM-SFP28-25GBE-SR-1-MLN support DOM optical diagnostics?
Yes. Digital diagnostics follow SFF-8472 and surface temperature, supply voltage, TX bias, TX power, and RX power. Values are readable through mstflint on Mellanox OFED, ethtool -m on Linux, and Supermicro IPMI for server-side visibility. The DOM baseline is captured per serial at EdgeOptic before shipment for reference against field values.
