400G QSFP-DD to 2*200G QSFP56 DAC

QSFP-DD (Double Density) has eight-channel electrical interfaces, with data transmission rates up to 28Gbps NRZ or 56Gbps PAM4, and total data rates up to 200Gbps or 400Gbps. QSFP-DD connectors and cable assemblies comply with IEEE 802.3bj, InfiniBand EDR and SAS 3.0 specifications, so they are suitable for various next-generation technologies and applications QSFP56 passive cable assembly products, based on 4X50G or 4X56G structure, can well meet the application requirements of next-generation 200G switches, servers, routers and other products. QSFP56 cable assemblies are optimized to reduce crosstalk and insertion loss, and have good signal integrity, fully complying with the next-generation 200G Ethernet and InfiniBand HDR standards.
