    Specifications

    NVIDIA/Mellanox MMS1X00-NS400 Compatible 400G QSFP112 DR4 InfiniBand NDR Optical Transceiver Module (1310nm, 500m, MPO-12 APC Connector, SMF, 0℃ to +70℃, DDM)

     

    The NVIDIA/Mellanox MMS1X00-NS400 Compatible 400GBASE-DR4 QSFP112 transceiver module supports a max data rate of 425Gbps. It enables the fiber link of 500m over SMF with an MPO-12 APC connector. QSFPTEK manufactured 400GBASE-DR4 QSFP112 complies with QSFP112 MSA Rev2.0, IEEE802.3ck standard 400GAUI-4 C2M electrical interface, IEEE 802.3 standard 400GBASE-DR4 optical interface, CMIS Rev5.0, etc. DDM function is supported on the 400G fiber optic transceiver to achieve real-time operating parameters monitoring. Adopting the Pulse-amplitude Modulation (PAM4) electrical and optical modulation, the Datacenter Reach 4-channel (DR4) QSFP112 achieves 400 Gigabit Ethernet through 4-channels of 100G-PAM4.

     

    This 400G DR4 QSFP112 supports both InfiniBand NDR (IB) and Ethernet (ETH). While not for use in switches, it is designed for insertion into 400Gb/s ConnectX-7/QSFP112-based PCIe-bus network cards or BlueField-3/QSFP112 Data Processing Units (DPUs) to twin-port 800G transceivers in 2x400G IB/EN switches. Its most typical application scenario is: A pair of single-port flat top 400G DR4 QSFP112 (MMS1X00-NS400) is independently connected to one of the connectors of the twin-port  800G 2x400G 2DR4 OSFP (MMS4X00-NS) module in a Quantum-2 InfiniBand or Spectrum-4 Ethernet switch.

      We tested this module before moving into a larger deployment and were satisfied with the overall results. It provided the bandwidth capacity we needed and helped our team confirm the design direction for the next stage of the network upgrade.

      We selected this module for a high-density switch environment where space efficiency was an important consideration. It helped us maximize available ports while keeping the overall network design clean and organized.

      The MMS1X00-NS400 is a Silicon Photonics module, and I’ve had mixed luck with SiPh stuff from other vendors in the past. But once it finally showed up and I got it installed in my ConnectX-7 adapter? Total relief. The quality is way better than I expected for the price. If they could just speed up the fulfillment a bit, I’d give them a perfect score. But for the product itself? No complaints. I’ll be back for more.
