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 concurrently. Vcc Rx, Vcc1 and
    Vcc Tx may be internally connected within the QSFP transceiver module in any  combination. The connector pins are each rated
    for a maximum current of 500 mA.
 3. No used.
