Note 1: GND is the symbol for signal and supply (power) common for the QSFP+ module. All are common within
the QSFP+ module and all module voltages are referenced to this potential unless otherwise noted. Connect
these directly to the host board signal-common ground plane.
Note 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 in Table 6. Recommended
host board power supply filtering is shown in Figure 4. Vcc Rx Vcc1 and Vcc Tx may be internally connected within the QSFP+ Module module in any combination. The connector pins are each rated for a maximum current of
500 mA.
