Mellanox compatible MMA2P00-AS Description
EdgeOptic's MMA2P00-AS compatible is a Mellanox-coded 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: 100m on OM4/OM5, 70m on OM3. Line signaling rate is 25.78125 GBd. 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). Duplex LC/UPC connector, DOM per SFF-8472. Power consumption is 0.3W maximum, versus the OEM rated at 1.0W, a meaningful thermal saving when a leaf switch is fully populated with 48 SFP28 ports.
MMA2P00-AS is the standard 25GbE optic across the Mellanox/NVIDIA ecosystem. On the server NIC side: Mellanox ConnectX-4 Lx EN, ConnectX-5 EN, and ConnectX-6 Dx. On the switch side: NVIDIA Spectrum SN2010, SN2100, SN2410, SN2700 (25G top-of-rack leaves), and the SN3800 spine family running 25G breakouts off 100G ports. 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 degrees Celsius case. The extended-temperature sibling, MMA2P00-ASHT, is a separate SKU for industrial and uncontrolled-ambient environments where the commercial-temp case rating is not sufficient. Specify MMA2P00-AS for standard data center and enterprise environments where intake air is controlled. For industrial or uncontrolled-ambient deployments or outdoor-adjacent cabinet deployments, specify MMA2P00-ASHT.
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 tooling on the host, through the switch CLI on Cumulus Linux or Onyx, and via standard SFF-8472 I2C reads on any EEPROM-aware host. Operating temperature range is 0 to 70 degrees Celsius case. Every MMA2P00-AS is pre-tested on ConnectX and Spectrum reference hardware before dispatch.

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 degrees Celsius 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 (850nm VCSEL, 100m 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 MMA2P00-ASHT datasheet 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.
