Note1: 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.
Note2: Vcc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power supplies and shall be applied concurrently.
