    NVIDIA/Mellanox MMS4X00-NM-T (980-9I30G-F4NM00) Compatible 800GBASE-DR8 (2x400G DR4) OSFP IHS/Finned Top PAM4 Optical Transceiver Module (1310nm, 500m, 2x MPO-12/APC Connectors, SMF, 0℃ to +70℃, DDM)

     

    NVIDIA/Mellanox MMS4X00-NM-T (980-9I30G-F4NM00) Compatible 800GBASE-DR8 (2x400G DR4) OSFP finned-top transceiver module supports a max data rate of 850Gbps. It enables the fiber link of 500m over single-mode fiber (SMF) with dual MPO-12 APC connectors. QSFPTEK manufactured  800GBASE-DR8 (2x 400GBASE DR4) OSFP complies with IEEE 802.3cu-2021 8x100GBASE-DR optical interface, IEEE P802.3ck D3.0 8x100GAUI-1 C2M electrical interface, OSFP MSA HW Rev 4.1, CMIS Rev 5.0. DDM (digital diagnostics monitoring) function is supported on the 800G fiber optic transceiver to achieve real-time operating parameters monitoring. Adopting the Pulse-amplitude Modulation (PAM4) modulation, the 2DR4 OSFP achieves 800 Gigabit Ethernet through 8x 106.25 PAM4 Retimed 2x400GAUI-4 C2M electrical interface.

     

    The 800G DR8 is an Ethernet (EN) 800Gb/s 2x400Gb/s Twin-port OSFP. The OSFP-IHS with finned top design is used in Spectrum-4 Ethernet air-cooled switches to switches, ConnectX-7 and BlueField-3 DPUs. QSFPTEK NVIDIA compatible optics are 100% tested in NVIDIA Ethernet host devices, ideal for Ethernet NDR end-to-end systems.
