Brand: NVIDIA / Mellanox Compatible Original Equivalent

Transceiver Module : NVIDIA/Mellanox MMS4X00-NM-FLT Compatible 800G 2xDR4 / DR8 InfiniBand NDR & 800G Ethernet Optical Transceiver Module, Twin-port OSFP Form Factor, 1310nm Wavelength, Single-Mode Fiber (SMF), Up to 500m Reach, Dual MPO-12/APC (MTP/MPO) Optical Connectors, DOM Support, RHS / Flat Top Shell

The MMS4X00-NM-FLT (980-9I301-00NM00 / OSFP-800G-2DR4XH) is a high-performance 800Gb/s (2x400Gb/s) Twin-port OSFP optical transceiver designed specifically for liquid-cooled AI data centers, supercomputing clusters, and high-density server environments. Featuring two internal 4-channel 400G engines (2xDR4 / DR8 parallel single mode) operating with 100G-PAM4 modulation over 1310nm wavelength, this module delivers high-bandwidth, ultra-low-latency data transmission up to 500 meters over Single-Mode Fiber (SMF).

Engineered with a Riding Heat Sink (RHS / Flat-Top) OSFP enclosure, the MMS4X00-NM-FLT is optimized for direct attachment inside liquid-cooled systems and high-density compute nodes, such as NVIDIA DGX H100 systems and 800G Network Interface Cards (NICs). Equipped with dual MPO-12/APC (MTP/MPO) optical connectors, it effectively doubles port density in 32-OSFP cages (supporting up to 64x 400G links) and provides seamless connectivity for 800G NDR Switch-to-DGX Server and Switch-to-NIC architectures.

Key Features

• RHS / Flat-Top Form Factor: Purpose-built flat-top enclosure tailored for liquid-cooled architectures, DGX H100 systems, and high-density server trays.
• 800Gbps Twin-Port Architecture: Houses two independent 400Gb/s optical engines (8x 106.25Gb/s PAM4 electrical) inside a single OSFP slot.
• Extended 500m Datacenter Reach: Enables reliable 2xDR4/DR8 parallel single-mode transmission up to 500 meters using 8 single-mode fibers.
• Dual MPO-12/APC Optical Interface: Employs two 4-channel MPO-12/APC connectors for low-loss, high-precision single-mode fiber connectivity.
• 100% NVIDIA System Interoperability: Fully verified for seamless operation in NVIDIA InfiniBand NDR and 800G Ethernet platforms across multiple firmware releases.
• Low Power & Full Diagnostics: Consumes ≤16W operating power while providing real-time Digital Optical Monitoring (DOM), CMIS 4.0, and RoHS compliance.
