Transceiver Module : NVIDIA/Mellanox MMA4Z00-NS-FLT Compatible 800G 2xSR4 / SR8 InfiniBand NDR & 800G Ethernet Optical Transceiver Module, Twin-port OSFP Form Factor, 850nm Wavelength, Multimode Fiber (MMF), 30m (OM3) / 50m (OM4) Reach, Dual MPO-12/APC Optical Connectors, DOM Support, RHS / Flat Top Shell
The MMA4Z00-NS-FLT (980-9I51A-00NS00 / OSFP-800G-2SR4FH) is an enterprise-grade 800Gb/s (2x400Gb/s) Twin-port OSFP optical transceiver built for high-density AI supercomputing, liquid-cooled data centers, and High-Performance Computing (HPC) environments. Built with premier Broadcom DSP and Broadcom VCSEL hardware, this parallel multimode module integrates two independent 4-channel 400G engines (2xSR4 / SR8) using 100G-PAM4 modulation over 850nm wavelength to deliver exceptional signal integrity and low Bit Error Rates (BER).
Engineered with a Riding Heat Sink (RHS / Flat-Top) OSFP shell, the MMA4Z00-NS-FLT is specifically optimized for liquid-cooled server architectures and compute tray interconnects, such as NVIDIA DGX H100 Cedar-7 systems, while maintaining full compatibility with Quantum-2 (QM9700/QM9790) and Spectrum-4 fabrics. Utilizing dual MPO-12/APC optical connectors, it supports up to 50 meters transmission over OM4 multimode fiber across direct switch-to-switch links or multi-HCA breakout setups.
Key Features
- Broadcom DSP & VCSEL Silicon: Powered by industry-leading Broadcom hardware to ensure low power consumption, superior signal stability, and strict adherence to IBTA BER standards.
- 800Gbps Twin-Port Architecture: Operates as two independent 400Gb/s transceiver engines (8x 106.25Gb/s PAM4 electrical) inside a single OSFP slot.
- RHS / Flat-Top Form Factor: Purpose-built flat-top enclosure tailored for liquid-cooled server trays, high-density environments, and NVIDIA DGX H100 Cedar-7 links.
- Dual MPO-12/APC Optical Interface: Two 4-channel MPO-12/APC optical connectors support short-reach parallel single/multimode fiber cabling (30m OM3 / 50m OM4).
- Broad Network Interoperability: 100% verified compatible with NVIDIA Quantum-2 and Spectrum-4 platforms for IB NDR and 800G Ethernet compliance.
- Energy Efficient & Compliant: Low power consumption (≤14W max) with Digital Optical Monitoring (DOM), CMIS 4.0, OSFP MSA, and RoHS compliance.
