Mellanox compatible MMA2L20-AR Description
EdgeOptic's MMA2L20-AR compatible is a Mellanox-coded version of the EdgeOptic 25G-SFP28-10 multi-vendor 25GBASE-LR transceiver. It carries the same one universal optical engine that ships across multiple vendor codes, with the EEPROM programmed so Mellanox and NVIDIA networking gear identifies it as a native MMA2L20-AR. The module runs 25 Gigabit Ethernet over duplex single-mode fiber at a 1310 nm nominal wavelength, reaching 10 km in line with IEEE 802.3cc and the SFP28 MSA.
Optically, the transceiver uses a DML laser transmitter and a PIN photodiode receiver. Launch power runs from a minimum of −7 dBm to a maximum of +2 dBm, and receiver sensitivity is rated at −12 dBm with an overload point of +3 dBm. That set of figures gives a 5 dB optical path loss budget over the 10 km single-mode span. The module connects through a duplex LC interface and operates across the standard commercial case temperature range of 0 to 70 °C, drawing up to 1.2 W. Digital diagnostics are supported per SFF-8472, so host equipment can read live temperature, supply voltage, laser bias, and optical power.
The OEM MMA2L20-AR is documented by NVIDIA as a 25GBASE-LR module, with 10G operation available by disabling retiming through host firmware or hardware control. The EdgeOptic 25G-SFP28-10 platform behind this compatible carries the full dual-rate envelope, supporting 25G Ethernet at 25.78 Gbps and 10G Ethernet at 10.31 Gbps; which rate is active depends on the host port configuration. The module does not run forward error correction on its own. Where the link requires RS-FEC, the host applies it, which keeps this part compatible with standard 25GBASE-LR deployments. Common applications include data center site interconnects, mobile backhaul, and service provider aggregation.
This compatible works on Mellanox and NVIDIA ConnectX and BlueField based platforms; verify port assignment against the host transceiver table before deployment. The module is CE and RoHS certified and built to the SFP28 MSA, SFF-8431, SFF-8432, and SFF-8472 specifications.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, the MMA2L20-AR compatible ships next business day from EU stock with a lifetime warranty. For volume pricing or coding questions, contact our sales team.
Frequently Asked Questions
Does the Mellanox MMA2L20-AR compatible run in both 25G and 10G ports?
The module carries the dual-rate 25G-SFP28-10 optical engine and supports 25G Ethernet at 25.78 Gbps and 10G Ethernet at 10.31 Gbps. NVIDIA documents the MMA2L20-AR as a 25GBASE-LR part where 10G operation is reached by disabling retiming through host firmware or hardware control. The active rate follows the host port configuration, so confirm the port mode on the switch or adapter before deployment.
Is the MMA2L20-AR compatible locked to Mellanox switches, or can it run on other hosts?
EdgeOptic ships this part with Mellanox-recognized EEPROM coding, so Mellanox and NVIDIA networking equipment identifies it as a native MMA2L20-AR. If a different vendor's host is involved, the optic needs that vendor's coding instead, which EdgeOptic supplies as a separate compatible. Match the coding to the brand of the host platform rather than the fiber plant.
