Mellanox compatible MFM1T02A-T Description
EdgeOptic's Mellanox MFM1T02A-T compatible is a Mellanox-coded 10GBASE-T copper SFP+ transceiver intended for the pre-acquisition Mellanox installed base, primarily ConnectX-3 and ConnectX-4 generation NICs along with the Mellanox-branded equipment sold before the 2020 Nvidia acquisition. The part continues to ship following the rebrand, and this page serves engineers who source against Mellanox-labelled documentation, OFED driver release notes, and the installed base of ConnectX-3 / ConnectX-4 host adapters in deployment. EdgeOptic programs the module EEPROM with Mellanox-recognised vendor identity so those hosts accept it under their standard vendor validation.
The module operates per IEEE 802.3an for 10GBASE-T and IEEE 802.3bz for multi-rate auto-negotiation at 2.5GBASE-T and 5GBASE-T, with IEEE 802.3ab fallback to 1000BASE-T. Reach is up to 30 m on Cat6a or Cat7 unshielded twisted-pair. The electrical and management interfaces follow SFF-8431, SFF-8432, and SFF-8472. Operating temperature covers 0 to 65 °C commercial grade, with CE and RoHS certification. The module draws more power than a fibre SFP+, and ConnectX NICs negotiate high-power SFP+ mode automatically on 10GBASE-T capable cages.
Because the MFM1T02A-T is a copper module, DOM telemetry is scoped to the fields that apply to a non-optical SFP+: case temperature, supply voltage, and link status. There is no laser, so transmit optical power, receive optical power, and laser bias current do not exist on this part and are not reported. Inventory tooling on Mellanox OFED hosts that expects optical DDM values should be configured to treat this module as a copper transceiver.
Primary deployment context for this page is host-side adapter use on ConnectX-3, ConnectX-3 Pro, and ConnectX-4 generation NICs running Mellanox-branded firmware and OFED release notes. ConnectX-3 cards generally enforce less strict vendor validation than newer generations; ConnectX-4 enforces Mellanox EEPROM coding, which EdgeOptic supplies here. New procurement targeting current Nvidia ConnectX-5 and ConnectX-6 Lx NICs, DOCA-era tooling, or the current Nvidia brand identity belongs on the Nvidia MFM1T02A-T compatible page, which is EEPROM-coded for the current Nvidia vendor string.

Frequently Asked Questions
Is the Mellanox-coded MFM1T02A-T different from a Nvidia-coded MFM1T02A-T, and which should I order?
The physical hardware is identical — MFM1T02A-T is a single SKU that Nvidia continues to ship following the 2020 Mellanox acquisition. The difference sits in the EEPROM vendor string. EdgeOptic supplies a Mellanox-coded variant on this page for deployments built around pre-acquisition Mellanox-branded equipment and Mellanox OFED documentation, and a Nvidia-coded variant on the Nvidia MFM1T02A-T compatible page for current Nvidia Networking deployments. ConnectX-3 and ConnectX-4 hosts that predate the rebrand are the primary fit for the Mellanox-coded variant; current ConnectX-5 / ConnectX-6 Lx hosts running DOCA generally expect the Nvidia-coded string.
Will a Mellanox-coded MFM1T02A-T work in a ConnectX-3 or ConnectX-4 NIC, including Dell or HPE OEM-rebranded variants?
EdgeOptic's Mellanox-coded EEPROM is recognised by Mellanox-branded ConnectX-3, ConnectX-3 Pro, and ConnectX-4 adapters under their standard vendor validation. ConnectX-3 generation cards historically enforce less strict transceiver checks than ConnectX-4 and newer, and both generations accept this module without a vendor-override step. Dell, HPE, and Supermicro OEM-rebranded ConnectX NICs built on the same Mellanox silicon are common in enterprise fleets; those OEM variants may enforce OEM-specific validation rather than the Mellanox vendor string, so confirm the expected EEPROM identity in the server vendor's qualified transceiver list before deploying into OEM-branded hosts.
