    Specifications

    Generic Compatible 200G QSFP-DD to 8 x 25G SFP28 Twinax DAC Breakout Splitter Cable (2.5m, Passive, 28AWG, 0-70°C, QSFP-DD to SFP28)

     

    The Generic compatible 200G QSFP-DD to 8 x 25G SFP28 breakout DAC provides connectivity between system units with a 200Gb/s QSFP28 connector on one side and eight separate 25Gb/s SFP28 connectors on the other. The 200G direct attach copper splitter cable is a high-speed and cost-effective alternative to 200Gb/s and 25Gb/s fiber optics, offering an affordable Ethernet connectivity solution for high-performance computing (HPC) environments.

     

    Optimized for short-reach connectivity, it is used for linking switches, routers, servers, and storage racks — both within and between adjacent racks. It delivers 200G transmission via 8 transmit and 8 receive channels, fully compliant with QSFP-DD MSA, SFF-8432, IEEE 802.3bs-200GAUI-8, IEEE802.3by-25GAUI, CMIS 4.0, and SFF-8472 standards.
