    Specifications

    NVIDIA/Mellanox MMS4C11 (980-9IAU1-00XM00) Compatible 1.6T DR8 (2x 800G DR4) OSFP224 RHS/Flat Top PAM4 Twin-port SiPh-Based Optical Transceiver Module (1310nm, 500m, 2x MPO-12/APC Connectors, SMF, 0℃ to +70℃, DDM)

     

    NVIDIA/Mellanox MMS4C11 (980-9IAU1-00XM00) compatible 1.6T OSFP224 DR8 (2x DR4) is an Ethernet twin-port SiPh-based transceiver module with dual MPO-12 APC connectors at 800Gb/s each. It enables the fiber link of 500m at 2x800Gb/s over single-mode fiber (SMF). With the Pulse-amplitude Modulation (PAM4) modulation, the Datacenter Reach 4-channel (DR4) OSFP adopts 8-channels of 200G-PAM4 electrical modulation and two ports of 4-channel 200G-PAM4 optical Parallel modulation.

     

    The 1.6T 2DR4 OSFP224 supports Ethernet end-to-end systems. Designed for supercomputing and HPC, the main application of this 1.6T OSFP transceiver is to link two 1.6T (2x800G) switches (i.e.Spectrum-6 SN6600-LD) together up to 500 meters or breakout to two 800G switches or two 800G network adpter cards  (i.e. ConnectX-8/OSFP) for storage or compute servers (i.e. DGX B300, B300 GPU). Its OSFP-RHS/Flat Top structure is designed for NVIDIA Spectrum-6 SN6600-LD Liquid-Cooled switches.
