splitter also reported for distance on or after 10 to 100 Km. In a hybrid GPON system
          WDM and TDM based systems integrated into a single network with aim to raise both the
          cost effectiveness and link capacity of the system.

          Photonics  technology  plays  a  key  role  in  the  emerging  fifth  generation  mobile
          communication systems. OFDM technique rapidly and commonly adopted in RF-wireless
          systems  for  instance  cell-networks  and  digital-audio  and  digital-video  broadcasting,
          because  it  combats  multipath  propagation  and  phase  distortion  effects.  OFDM  is  also
          second-hand  to  overcome  problems  of  multipath  fading  in  such  systems.  Hence
          combined  ROF-  OFDM  systems  implemented  in  the  existing  wireless  access  networks
          [12].  In  order  to  increase  the  spectral  efficiency  of  the  system,  OFDM  allows  the
          transmission  of  many  equalized  narrow-frequency  orthogonal  carriers  using  a  single
          complex multiplication process. OFDM is a compatible and cost-effective technology with
          ROF  based  systems  [63],  [64],  [65].  It  is  even  possible  to  combine  ROF  distribution
          antenna systems with used OFDM techniques with broadband access optical networks
          like  WDM-PON  [46],  [50],  [62].  Due  to  the  better  spectral  efficiency  value  than  other
          modulation techniques, QAM technique used with OFDM concept in our work.
