100GbE 100GBASE-SR4 Connectivity
The MMA1B00-C100 is designed for IEEE 802.3 100GBASE-SR4 Ethernet. It converts four electrical input lanes into four optical transmit lanes and converts four optical receive lanes back into electrical signals.
Each optical lane operates at approximately 25.78125GBd, with four lanes combined to provide the aggregate 100Gb/s link. NVIDIA's current specification confirms the 25.78125Gb/s per-lane signaling rate with retiming. ([NVIDIA](https://networking-docs.nvidia.com/mma1b00c100dspec/specifications))
850nm Multimode Fiber
The MMA1B00-C100 uses a nominal 850nm optical wavelength and is designed for parallel multimode fiber. This makes it particularly suitable for short-distance data-center applications.
Unlike 100GBASE-LR4 or PSM4 modules that use single-mode fiber, SR4 optics are optimized for multimode fiber and high-density short-reach links.
MPO/MTP Connector
The optical interface uses an MPO/MTP multi-fiber connector. The four transmit and four receive channels require a parallel-fiber connection rather than the duplex LC connector commonly found on 10GbE LR or 100GbE LR4 modules.
Use a compatible multimode MPO/MTP fiber assembly with the correct polarity and fiber configuration for the installed network architecture.
Transmission Distance
At 100Gb/s, NVIDIA specifies up to 100 meters on OM4 multimode fiber and up to 70 meters on OM3 multimode fiber. At 40Gb/s, the module can support up to 100 meters on OM3. :contentReference[oaicite:2]{index=2}
The actual supported distance depends on fiber quality, connector loss, link budget, installation practices and the capabilities of both connected devices.
QSFP28 Form Factor
The MMA1B00-C100 uses the high-density QSFP28 form factor. QSFP28 allows four high-speed electrical lanes within a compact module footprint, making it well suited to high-density 100GbE switches and network adapters.
The module is hot-pluggable and uses a single 3.3V supply. NVIDIA specifies QSFP28 Power Class 3 operation. :contentReference[oaicite:3]{index=3}
Digital Diagnostic Monitoring
The transceiver supports SFF-8636 Digital Diagnostic Monitoring. Supported monitoring includes optical transmit and receive power, laser bias current, supply voltage and module case temperature. :contentReference[oaicite:4]{index=4}
These diagnostics help network administrators monitor optical link health and troubleshoot fiber connectivity issues.
Low Power Consumption
NVIDIA specifies typical power consumption of approximately 2.2W with retiming enabled, with a maximum of 2.5W. Without retiming, the typical power consumption is approximately 1.5W. :contentReference[oaicite:5]{index=5}
This low-power design is useful for high-density data-center environments where many 100GbE ports operate simultaneously.
Selectable Retiming
The MMA1B00-C100 family supports selectable transmit and receive retiming. Retiming can help maintain signal integrity across supported high-speed electrical interfaces.
NVIDIA's current documentation specifies retiming support for both transmit and receive paths and programmable Tx input equalization and Rx output amplitude/emphasis. :contentReference[oaicite:6]{index=6}
NVIDIA Ethernet Compatibility
NVIDIA specifies the MMA1B00-C100D successor/variant as qualified for use in NVIDIA Ethernet end-to-end systems. Older Mellanox firmware documentation explicitly lists MMA1B00-C100 as a validated 100GbE QSFP28, MPO, 850nm transceiver with up to 100m reach. :contentReference[oaicite:7]{index=7}
Exact compatibility depends on the switch, network adapter, firmware and transceiver revision. Always verify the specific hardware combination before deployment.
