Notes:
1. GND  is the symbol for signal and supply (power) common for the QSFP28  module . All are common within  the  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.  VccRx ,  Vcc1  and  VccTx  are  the  receiving  and  transmission  power  suppliers  and  shall  be  applied concurrently. Recommended host board power supply filtering is shown below . Vcc Rx , Vcc1 and VccTx may be internally connected within the module in any combination . The connector pins are each rated for a maximum current of 2000mA.
