    Specifications

    NVIDIA/Mellanox MMS4X00-NM-HGX (980-9I302-00NM00) Compatible 800G DR8 OSFP RHS/Flat Top PAM4 Twin-port Ethernet Optical Transceiver Module (1310nm, 500m, 2x MPO-12/APC Connectors, SMF, 0℃ to +70℃, DDM)

     

    NVIDIA/Mellanox MMS4X00-NM-HGX (980-9I302-00NM00) compatible 800G DR8 (2x400G DR4) OSFP is an Ethernet twin-port transceiver module with dual MPO-12 APC connectors at 400Gb/s each. It enables the fiber link of 500m at 2x400Gb/s over single-mode fiber (SMF). With the Pulse-amplitude Modulation (PAM4) modulation, the 2xDR4 OSFP adopts 8-channels of 100G-PAM4 electrical modulation and two ports of 4-channel 100G-PAM4 optical Parallel modulation.

     

    With a flat top design, the OSFP-RHS is offered for Rubin NVL8 Systmes. Its main application is to link the NVIDIA DGX Rubin NVL8 Systmes to Spectrum-4 and Spectrum-5 switches. QSFPTEK NVIDIA InfiniBand compatible optics are 100% tested in NVIDIA host devices, ideal for Ethernet end-to-end systems.

    • I want to connect this QSFP-DD 800G 2FR4 module to my 400G switches, which 400G optics and fiber patch cable should I use?
      Hello, to connect the QSFP-DD 800G 2FR4 module to 400G switches, you can use QSFP-DD-400G-FR4 for 400G switches. Since QSFP-DD 800G 2FR4 has two duplex CS connectors while QSFP-DD-400G-FR4 has a single duplex LC connector, you should link QSFP-DD 800G 2FR4 to two QSFP-DD-400G-FR4 via two CS to LC Duplex OS2 single mode fiber. Please kindly check the application section of the product details page.
    • The 800G 2FR4 optical module has two separate connectors, can I use only one port of the module?
      Yes, if only one of the ports is used, the rate is 400G.
    • Can I plug 400G OSFP modules into 800G OSFP ports?
      Yes, 800G OSFP ports are backward compatible with 400G OSFP as long as the physical form factor is compatible.
