Brand: NVIDIA / Mellanox Compatible Original Equivalent

Optical Transceiver : NVIDIA/Mellanox MMA1L30-CM (QSFP-100G-CWDM4H) Compatible 100GBASE-CWDM4 / InfiniBand EDR QSFP28 Optical Transceiver Module, 1310nm CWDM EML Transmitter, PIN Receiver Array, Up to 2km Reach over Single-Mode Fiber (SMF), Duplex LC Connector, DOM/DDM Support, 4x25.781Gb/s NRZ Electrical/Optical Modulation, Max Power Consumption ≤3.5W

The MMA1L30-CM (QSFP-100G-CWDM4H) is a high-performance 100Gb/s 4-channel QSFP28 optical transceiver module designed for intermediate-reach High-Performance Computing (HPC) networks, enterprise data centers, and high-density spine-leaf architectures. By multiplexing 4 CWDM optical channels operating at 25.781Gb/s NRZ over duplex single-mode fiber (SMF), this module delivers reliable, low-latency transmission up to 2km using standard Duplex LC connectors.

Built for robust operational stability, the MMA1L30-CM is fully compliant with InfiniBand EDR protocols, CWDM4 MSA specifications, IEEE 802.3bm CAUI-4, and 100G Ethernet standards. Featuring integrated Digital Diagnostic Monitoring (DOM/DDM) accessible via the I2C interface, it allows network administrators to perform real-time monitoring of critical operational parameters. It is 100% verified for seamless plug-and-play interoperability with NVIDIA SB7800 / SB7890 EDR InfiniBand Switches and ConnectX-5 / ConnectX-6 Network Interface Cards (NICs).
