1: GND is the symbol for signal and supply (power) common for the QSFP28 module. All arecommon within the QSFP28 module and all module voltages are referenced to this potential unlessotherwise noted. Connect these directly 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. Requirements defined for the host side of the Host Edge Card Connector are listed inTable 6. Recommended host board power supply filtering is shown in Figures 3 and 4. Vcc Rx Vcc1and Vcc Tx may be internally connected within the QSFP28 Module in any combination. Theconnector pins are each rated for a maximum current of 500mA.
