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.
2. Vcc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power supplies and shall be applied concurrent- ly. 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 with- in the QSFP+ Module module in any combination. The connector
pins are each rated for a maximum current of 500 mA.
