Increasing Optical Power OLT MA5608T

Hi,

Is possible increasing optical power to GPON port in OLT MA5608T? If yes, which command I can use for do it?*

This is my product:

MA5608T(config)#display board 0

  SlotID  BoardName  Status          SubType0 SubType1    Online/Offline

  0       H807GPBD   Normal                           

  1     

  2

  4       H801MPWD   Normal
