    Specifications

    Generic Compatible 400G QSFP-DD DR4 to 4x QSFP28 DR1 Breakout Active Optical Cable (20m, Actiive, 0-70°C, QSFP-DD to QSFP28)

     

    The 400G QSFP-DD DR4 to 4xQSFP28 DR1 SMF active optical breakout cable is used in 4x 100 Gigabit Ethernet links over OS2 single mode fiber, which provides connectivity between system units with a 400GbE connector on one side and four separate 100GbE connectors on the other four sides. The cable connects data signals from each of the 8 SMFpairs on the single QSFP-DD end to the dual pair of each of the QSFP28 multiport ends. Host FEC is required to support up to 500m fiber transmission.

     

    The active optical splitter cable is compliant with the QSFP-DD-MSA and with 100GBASE-DR1 specification, they are ideal for data centers and cloud networks.
