Optical Transceiver : NVIDIA/Mellanox MMA1L10-CR Compatible 100GBASE-LR4 / InfiniBand EDR QSFP28 Optical Transceiver Module, 1310nm LAN-WDM DFB Transmitter, PIN Receiver Array, Up to 10km Reach over Single-Mode Fiber (SMF), Duplex LC Connector, DOM/DDM Support, 4x25.781Gb/s NRZ Electrical/Optical Modulation, Max Power Consumption ≤4.5W
The MMA1L10-CR (980-9I17P-00CR00) is an enterprise-grade 100Gb/s 4-channel QSFP28 optical transceiver module optimized for long-reach High-Performance Computing (HPC) fabrics, campus backbones, and high-density spine-leaf data center architectures. Converting 4 independent 25Gb/s electrical input channels into 4 LAN-WDM optical signals and multiplexing them onto single-mode fiber, this module delivers lossless long-distance transmission up to 10km using standard Duplex LC connectors.
Engineered for high reliability, the MMA1L10-CR is fully compliant with InfiniBand EDR protocols, 100GBASE-LR4 IEEE 802.3ba, and CAUI-4 IEEE 802.3bm standards. Equipped with built-in Digital Optical Monitoring (DOM/DDM) via the I2C interface, it enables real-time diagnostic performance monitoring. It is 100% verified for seamless interoperability with NVIDIA SB7800 / SB7890 EDR InfiniBand Switches and ConnectX-5 / ConnectX-6 Network Interface Cards (NICs).
Key Features
- Long-Reach 100G Transmission: Supports high-speed 100Gb/s optical links up to 10km over single-mode fiber (SMF) via 4x 25G LAN-WDM multiplexing.
- Integrated LAN-WDM Architecture: Utilizes 1310nm band DFB laser transmitters and PIN photodetector receivers for low-dispersion long-haul performance.
- Real-Time Digital Diagnostic Monitoring (DOM): Allows continuous tracking of laser bias current, optical output power, received optical power, module temperature, and supply voltage.
- Standard Duplex LC Interface: Designed with standard Duplex LC fiber connectors for simple integration into existing single-mode patch cabling.
- Low Latency & High Density: Purpose-built for HPC, AI clusters, and cloud environments requiring high throughput and ultra-low latency.
- 100% NVIDIA/Mellanox Compatibility: Fully tested and compliant with QSFP28 MSA, IBTA Industrial BER standards, IEEE 802.3ba/bm, and RoHS protocols.
