Supermicro compatible AOM-SFP28-25GBE-SR-INT Description
EdgeOptic's AOM-SFP28-25GBE-SR-INT compatible is an Intel-coded 25GBASE-SR SFP28 transceiver, a direct replacement for Supermicro's AOM-SFP28-25GBE-SR-INT. The -INT suffix designates the Intel EEPROM variant, paired with Supermicro server NICs built around Intel XXV710 and E810 silicon.
The module operates at 25GBASE-SR over duplex MMF: 100m on OM4/OM5, 70m on OM3. Transmit power is -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, with a 5.3 dB link budget using host RS-FEC (IEEE 802.3by Clause 108). 850nm VCSEL transmitter, PIN photodiode receiver, LC/UPC duplex connector, DOM per SFF-8472. Line rate spans 8.5 to 25.78 Gbps, so the same module runs 10GBASE-SR or 25GBASE-SR depending on host port speed. Power draw is 0.3W maximum.
Supermicro markets the AOM optic family in paired INT and MLN variants. The -INT variant (this SKU) targets Supermicro AOC server NICs built on Intel silicon (XXV710 and E810 chipsets). The sibling -1-MLN variant targets Supermicro AOC cards built on Mellanox ConnectX-4 Lx silicon. INT and MLN are not interchangeable on hosts that enforce EEPROM validation, so the suffix on the optic must match the NIC silicon family on the AOC card.
For Supermicro servers shipped with Intel-chip SFP28 NICs, the INT variant presents as a native Supermicro optic under standard EEPROM validation. For broader Intel NIC deployments outside the Supermicro AOC range (standalone Intel XXV710 adapters or Intel E810 reference NICs), the equivalent Intel-coded EdgeOptic part is LTF8505-BC-IN (E25GSFP28SR), a separate SKU.
Intel's E810 NVM firmware below revision 4.20 has documented 25G optical link-up issues independent of the optic. Supermicro AOC cards built on Intel E810 silicon inherit this firmware dependency through the Intel NIC driver, so confirming NVM 4.20 or later removes that variable before deployment. The INT-coded EEPROM itself resolves module-identification concerns; the host firmware version governs link stability below the EEPROM layer. XXV710-based AOC cards are not affected by this specific E810 firmware caveat.
DOM telemetry (transmit power, receive power, temperature, laser bias, supply voltage) is accessible via the Intel NIC driver through `ethtool -m <if>` on Linux. Supermicro BMC sensor data via IPMI or Redfish exposes chassis-level thermal and power telemetry, not NIC-side SFP DOM. Operating temperature range is 0 to 70 degrees Celsius case (commercial). Every AOM-SFP28-25GBE-SR-INT is pre-tested on Intel-silicon Supermicro AOC reference hardware before dispatch.

Frequently Asked Questions
What is the difference between AOM-SFP28-25GBE-SR-INT and AOM-SFP28-25GBE-SR-1-MLN?
The suffix indicates the EEPROM coding and therefore the AOC silicon family the optic is paired with. The -INT variant is coded for Intel silicon, pairing with Supermicro AOC cards built on Intel XXV710 or E810 NIC chips. The -1-MLN variant is coded for Mellanox ConnectX-4 Lx silicon. Optical specs (850nm, 100m OM4, 5.3 dB budget) are identical. The two part numbers are not interchangeable when the host enforces module validation. Match the suffix to the AOC chipset family.
Which Supermicro AOC NIC cards require the INT variant?
Supermicro AOC cards built on Intel silicon (Intel XXV710 or Intel E810 NIC chips) require the -INT variant. Supermicro AOC cards built on Mellanox ConnectX-4 Lx silicon require the -1-MLN variant. Specific AOC model lists depend on the generation and form factor (standard low-profile, OCP 3.0, multi-port); for a signed compatibility statement against a specific AOC model number, contact us with the AOC SKU on hand and we will confirm before shipment.
Does the AOM-SFP28-25GBE-SR-INT need a firmware update for E810-based AOC cards?
The module's Intel-coded EEPROM removes the 'uncertified module' diagnostic on Intel E810 NICs. Separate from EEPROM validation, Intel's community forum documents that E810 NVM firmware below revision 4.20 has 25G optical link-up issues regardless of the optic. Confirm that any E810-based Supermicro AOC card is running NVM 4.20 or later before deployment. Supermicro firmware bundles are typically current, but field servers that have not been patched recently should be verified. AOC cards built on Intel XXV710 silicon are not subject to this specific E810 firmware caveat.
