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 hostboard 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 in Table 6. Recommended host
boardpower 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.
