Product Detail:
 HYTOPTODEVICE NVIDIA/Mellanox MMS4X00-NS400 Compatible 400G OSFP DR4 Flat Top 1310nm 500m Optical Transceiver Module  
      The HYTOPTODEVICE MMS4X00-NS400 is a premium NVIDIA Mellanox compatible 400G OSFP DR4 optical transceiver module, purpose-built for ConnectX-7 HCA network adapters and next-generation AI/HPC interconnects. Operating at 400Gb/s (4x100G PAM4), this single-port 400g osfp dr4 module features a Flat Top (OSFP-RHS) design, essential for the "riding heat sink" cooling systems found in PCIe adapter cards.  Fully compliant with OSFP MSA and IEEE 802.3ck protocols, it uses 1310nm EML laser technology to deliver ultra-low-latency 400Gbps throughput over Single-Mode Fiber (SMF) up to 500 meters (with legacy 100m support). Featuring a single MPO-12/APC connector, this commercial-grade (0°C to 70°C) module is qualified for both InfiniBand NDR and 400G Ethernet environments. 400G OSFP DR4 manufacturer china HYTOPTODEVICE ensures 100% interoperability with NVIDIA Quantum-2 and Spectrum-4 fabrics, providing a stable long-term supply for hyperscale data centers.

  • NVIDIA ConnectX-7 NICs: CX713106A, CX713105A, and other OSFP-based network cards.

  • NVIDIA Quantum-2 Switches: QM9700 and QM9790 via breakout from Twin-port ports.

  • NVIDIA Spectrum-4 Switches: SN5600 800G Ethernet platforms.

  • NVIDIA BlueField-3 DPUs: Specialized OSFP-RHS interface deployments.

Primary Application Scenarios

  • InfiniBand NDR Connectivity: The standard transceiver for ConnectX-7 OSFP adapters, linking high-performance servers to Quantum-2 InfiniBand switches.

  • 800G to 2x400G Breakout: Perfectly pairs with 800G Twin-port OSFP modules (like MMS4X00-NS) to enable high-density switch-to-adapter fan-out configurations.

  • NDR200 Downshift Mode: Supports 2-fiber splitter cables to automatically operate in 200Gb/s NDR200 mode, reducing power consumption to approximately 5W.

  • AI GPU Clusters: Providing critical high-speed interconnects for NVIDIA HGX/DGX H100 and H200 nodes requiring Flat Top OSFP form factors.

FAQ for NVIDIA/Mellanox
 MMS4X00-NS400 Compatible SFP+Transceivers

Q1:What is OSFP-400G-DR4? A:The 400G OSFP DR4 is a hot pluggable optical transceiver module with a speed of 400Gbps, a wavelength of 1310nm, and a transmission distance of up to 500m with OM2 SMF. It is ideal for data centre, 400G Ethernet and Infiniband Interconnects.

Q2:What is the maximum transmission distance of the 400G OSFP DR4 transceiver?A:HYTOPTODEVICE OSFP 400G DR4 module supports the maxium transmitting distance of up to 500m with OS2 SMF.

Q3:What fiber connector is required for the NVIDIA/Mellanox  MMS4X00-NS400 ?A:The 400G OSFP DR4 module uses an MPO-12/APC connector. It is very important for 400G/800G single-mode links to use the APC (Angled Physical Contact) polish. that can minimize back-reflection and maintain signal quality.

Q4:What is the 800G DR8 vs 400G DR4 transceiver comparison?A:Both the OSFP 800G DR8 and OSFP 400G DR4 are SMF optic modules with a wavelength of 1310nm and a transmission distance up to 500m (OS2 SMF). The difference is that the 800G DR8 doubles the 800G speed by using eight 100Gbps channels, while the 400G DR4 has a speed of 400Gbps and uses four 100Gbps channels.

Q5:Does the HYTOPTODEVICE OSFP-400G-DR4 support breakout to 100G?A:Yes. The 400g osfp dr4 utilizes parallel DR4 architecture, supporting 4x100G breakout. that allows you to connect one 400G OSFP port to four separate 100G-DR QSFP ports with an MPO-12 breakout cable. 400G OSFP DR4 manufacturer china HYTOPTODEVICE support breakout to 100G.

Q6:Where to buy 400G OSFP DR4 SMF optical transceiver?A:There are many manufacturers that produce and sell 400G  fiber optical modules, but 400G OSFP DR4 manufacturer china HYTOPTODEVICE is the excellent provider: a source factory, fully controllable process, reliable performance, 100% compatible, sufficient inventory, fast delivery, and quick response.

Q7:The link is "Up" but I have high packet loss. Why? A:There could be two reasons,1. Dirty connectors:tiny dust particles can obstruct signal transmission. Please use  fiber optic cleaner to clean the connector. 2. Fiber optic cable bending: avoid  severe bending of the fiber optic cable.

Q8:Is the 400G OSFP DR4 backward compatible with lower-speed modules,such as 100G?A:Yes,The 400G DR4 is backward compatible with lower-speed optical transceivers, such as 200G,100G and 50G, but the performance will be reduced.

 Q9:How do HYTOPTODEVICE ensure 400G OSFP DR4 module compatibility with network switch?A:Ensuring 100% compatibility, optical modules must be coded to match the switch's requirements. Source-factory HYTOPTODEVICE was equipped with various high-speed switch,the brands include such as Cisco,NVIDIA,Huawei. highly professional in coding equipment for various brands to ensure they are recognized and running in your  device.
 
Q10:Is OSFP-400G-DR4 hot-swappable?A:HYTOPTODEVICE fiber transceiver modules are hot-pluggable, hot Pluggable OSFP MSA Compliant.you can plug or unplug the optical transceiver, while the device is powered on without damaging the hardware.

Q11:Why is the Flat Top (OSFP-RHS) design necessary?A: The 400G OSFP DR4 use the  Flat Top OSFP design for optimized thermal management, it is very important for adapter cards (like ConnectX-7), that use the riding heat sink on the connector cage for cooling, so that the pluggable transceiver stays within the 0°C to 70°C (32 to 158°F) operating temperature range.
