The QSFP56-200G-FR4 is based on PAM4 (Pulse Amplitude Modulation Four Levels) modulation technology, digital signal processing (DSP) chip, and QSFP56 design. The 200GBASE-FR4 QSFP56 transceiver complies with CMIS4.0, IEEE 802.3bs, QSFP MSA, and SFF-8665 standards. The QSFPTEK 200G NVIDIA InfiniBand optical device has been 100% tested on NVIDIA InfiniBand host devices, supporting dual Ethernet and InfiniBand HDR, and is highly suitable for end-to-end InfiniBand HDR systems. It is used in the QM8700 switch. In addition to Mellanox MMS1W50-HM , Liyuan Tech supply a wide range of other Optical transceiver transceivers.
