Radio over fiber technology is becoming increasingly important for wireless market in order to support the ever growing data
traffic volumes. By implementing RoF technology, the unique properties of optical fibre known for its low loss and high wide bandwidth
make it an ideal medium to transmit microwave signals to the Remote Site. It combines with PON and serves as high capacity wireless
distribution nodes. Meanwhile with the FTTH project deployment, the PON is counted as the good method to meet the challenge of the
fixed users. So the integration configuration of RoF with PON gets more researched, which is considered as a promising solution to offer
end users greater choice, convenience and high bandwidth services. Hybrid GPON is a hybrid passive optical network, where WDM GPON
and TDM-GPON are integrated into a single passive optical network, reducing cost and increasing the data rate. TWDM is the recent
technology for increasing capacity and to reduce the cost. In this paper we have explained this technology and simulated basic link for
25km.
