    1:   GND is the symbol for signal and supply (power) common for the QSFP28 module.   All are common within the

    QSFP28 module and all module voltages are referenced to this   potential unless otherwise noted. Connect thesedirectly to the host board   signal-common ground plane.

    2:   Vcc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power supplies and   shall be applied concurrently.

    Vcc Rx Vcc1 and Vcc Tx may be internally connected within the QSFP28   Module in any combination. The connector pins are each rated for a maximum   current of 500mA.
