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.
