Nvidia compatible MMA1L10-CR Description
EdgeOptic's MMA1L10-CR compatible is a NVIDIA (Mellanox) coded 100GBASE-LR4 QSFP28 transceiver, built on our 100G-QSFP28-10 hardware platform. MMA1L10-CR is the part number for the NVIDIA 100GbE QSFP28 LR4 client optic, qualified for NVIDIA InfiniBand and Ethernet systems including the SB7800 series switches and ConnectX-5 adapters. Each unit ships with NVIDIA/Mellanox-recognised EEPROM values pre-programmed, so the module identifies and initialises on these platforms cleanly. The module replaces NVIDIA OEM stock as a like-for-like spare or new-deployment client optic for 100G LR4 ports on the supported chassis.
Mellanox Technologies became part of NVIDIA in April 2020, and the optics catalogue migrated under the NVIDIA brand while the Mellanox part-number prefixes stayed in place. Engineers may encounter the same module called Mellanox MMA1L10-CR or NVIDIA MMA1L10-CR in BOMs and procurement portals; they refer to the same hardware. The MMA1L10-CR ordering reference covers NVIDIA InfiniBand EDR end-to-end systems and ConnectX-5 adapters per NVIDIA's published product brief.
Optically the module conforms to IEEE 802.3ba 100GBASE-LR4 with an IEEE 802.3bm CAUI-4 host interface per NVIDIA's specifications page. Four LAN-WDM channels at 1295.56, 1300.05, 1304.58 and 1309.14 nm each carry 25.78 Gbps NRZ on a single duplex LC SMF pair for an aggregate 103.125 Gbps line rate. The module supports an optical path loss budget of 6.3 dB on G.652 single-mode fiber for reach up to 10 km. The QSFP28 form factor follows MSA SFF-8665, and DDM/DOM telemetry is exposed via the SFF-8636 management interface for per-lane TX and RX optical power, supply voltage, module temperature and laser bias current. NVIDIA classifies the module as Power Class 4, drawing up to 3.5 W.
The duplex LC connector accepts standard SMF patch cords, and the module is hot-pluggable on a live host. The MMA1L10-CR ordering code refers to the standard 100GBASE-LR4 form; NVIDIA publishes other QSFP28 SKUs for short-reach and CWDM4 use cases under different part numbers. Verify the suffix against NVIDIA's transceiver catalogue when consolidating spares, since some related part numbers in the same family carry suffix variants that EdgeOptic indexes as separate SKUs.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For BOM verification or volume pricing, contact our sales team.
Frequently Asked Questions
Is MMA1L10-CR the same module under NVIDIA and Mellanox branding?
Yes. Mellanox Technologies merged with NVIDIA in April 2020, and the optics catalogue moved under NVIDIA's brand while the original Mellanox part numbers stayed in place. The MMA1L10-CR ordering code on a BOM refers to the same 100GBASE-LR4 QSFP28 hardware whether the document predates or postdates the brand transition. EdgeOptic's compatible matches both the original Mellanox and current NVIDIA EEPROM coding for this part.
Does the MMA1L10-CR compatible work with ConnectX adapters?
NVIDIA's published specifications for the MMA1L10-CR list NVIDIA InfiniBand EDR end-to-end systems and ConnectX-5 adapters as qualified hosts. EdgeOptic's compatible carries NVIDIA-recognised EEPROM coding for these qualified host platforms. For other ConnectX generations or MLNX-OS / Spectrum platform combinations not on the NVIDIA published qualified list, verify the configuration against NVIDIA's transceiver compatibility documentation before deployment.
Will the MMA1L10-CR compatible identify on NVIDIA / Mellanox switches without an override command?
EdgeOptic codes each unit with NVIDIA / Mellanox-recognised EEPROM values for the platforms NVIDIA qualifies for the MMA1L10-CR ordering code. For the qualified hosts in NVIDIA's product brief (the SB7800 series and ConnectX-5 adapters) the module identifies cleanly through the standard transceiver detection path. If a deployment uses an MLNX-OS or NVIDIA Cumulus Linux configuration with a third-party-optics policy, verify the policy state for that platform and software release before installation.
