Mellanox compatible MMA2P00-AS Description
EdgeOptic's MMA2P00-AS compatible is a Mellanox-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor 25GBASE-SR SFP28 transceiver, a direct replacement for NVIDIA/Mellanox's MMA2P00-AS optic. It ships with Mellanox-recognized EEPROM, so the module identifies as a native Mellanox part on ConnectX-series NICs and Spectrum switches under standard module-identification policies.
The module operates at 25GBASE-SR per IEEE 802.3by Clause 112 over duplex MMF: 100 m on OM4/OM5, 70 m on OM3. Line signaling rate is 25.78125 GBd. Transmit optical power is −5 to +2.4 dBm, receive sensitivity better than −10.3 dBm, with a 5.3 dB link budget. RS-FEC per IEEE 802.3by Clause 91 (RS(528,514)) is supported when enabled by the host port. Duplex LC/UPC connector, DOM per SFF-8472. The EdgeOptic compatible draws 0.3 W typical against the Nvidia-documented OEM 1.0 W maximum, a meaningful thermal saving on a fully populated 48-port leaf.
MMA2P00-AS is the standard 25GbE optic across the Mellanox/NVIDIA ecosystem. Works on Mellanox ConnectX-4 Lx EN, ConnectX-5 EN, and ConnectX-6 Dx server NICs and on NVIDIA Spectrum SN2010, SN2100, SN2410, and SN2700 25G top-of-rack switches, with the SN3800 spine family supporting 25G breakouts off 100G ports. Verify against Nvidia compatibility documentation for the specific NIC firmware and switch OS combination in your deployment. An end-to-end leaf-spine build with ConnectX NICs and Spectrum switches can standardize on this one part number for every 25G short-reach link.
The AS variant is the commercial-temperature model, rated 0 to 70 C case. The extended-temperature sibling MMA2P00-ASHT is a separate SKU for industrial and uncontrolled-ambient deployments where the commercial rating is not sufficient. Specify MMA2P00-AS for controlled data center and enterprise environments, MMA2P00-ASHT for outdoor-adjacent cabinets; confirm the extended-temperature range against the Nvidia MMA2P00-AS / MMA2P00-ASHT product brief before procurement.
Nvidia's MMA2P00-AS product brief cites IEEE 802.3bm in places. The applicable standard for 25GBASE-SR is IEEE 802.3by Clause 112. The optical media and host-side FEC behavior follow 802.3by, which is the reference EdgeOptic uses when validating the module against the 25G-SFP28-100 root specification.
DOM registers (transmit power, receive power, temperature, laser bias, supply voltage) are accessible through Mellanox OFED on the host, through the switch CLI on Cumulus Linux or Onyx, and via standard SFF-8472 I2C reads. Operating temperature range is 0 to 70 C case. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms.

Frequently Asked Questions
Does the Mellanox MMA2P00-AS work in non-Mellanox switches and third-party servers?
The MMA2P00-AS EEPROM is coded for Mellanox/NVIDIA platforms (ConnectX NICs, Spectrum switches), so those hosts identify it as a native optic. Third-party SFP28 hosts with strict EEPROM validation may not recognize Mellanox coding; behavior depends on the host's module-identification policy. For hosts that accept any compliant 25GBASE-SR module, the optical side is fully interoperable. If you need to deploy in a non-Mellanox host with strict validation, confirm compatibility with us before purchase.
What is the difference between MMA2P00-AS and MMA2P00-ASHT?
The difference is the operating temperature range. MMA2P00-AS is rated 0 to 70 C case (commercial temperature) for standard data center and enterprise deployments. MMA2P00-ASHT is the extended-temperature variant (HT = harsh temperature), targeted at industrial and uncontrolled-ambient environments where the commercial-temp case rating is not sufficient. The optical specs (850 nm VCSEL, 100 m OM4, 5.3 dB budget) are identical. The AS and ASHT part numbers are not substitutable in procurement systems that enforce temperature-class distinction; check the Nvidia MMA2P00-AS / MMA2P00-ASHT product brief at network.nvidia.com for the exact extended-temp range.
Can I deploy MMA2P00-AS across both Mellanox Spectrum switches and ConnectX-4 Lx server NICs?
Yes. MMA2P00-AS is the standard Mellanox-coded optic for both the switch side (Spectrum SN2010, SN2100, SN2410, SN2700) and the server side (ConnectX-4 Lx EN, ConnectX-5 EN, ConnectX-6 Dx). Standardizing on a single part number across leaf switches and server NICs simplifies spares inventory and removes reverse-compatibility ambiguity between module coding and host validation on end-to-end Mellanox fabrics. Verify the specific NIC firmware and switch OS revision against Nvidia compatibility documentation for your deployment.
