Notes:
1.GND is the symbol for signal and supply (power), Connect these directly to the host board signal
common ground plane
2.VccRx, Vcc1 and VccTx are the receiving and transmission power suppliers and shall be applied concurrently.
Vcc Rx, Vcc1 and Vcc Tx may be internally connected within the QSFP+, The connector pins are each rated for a
maximum current of 500mA.
