The combination of radio over fiber (RoF) and orthogonal
frequency division multiplexing (OFDM) techniques has resulted in a
high-data-rate at lower cost in the last mile of wireless networks. This paper
investigates the use of the OFDM as a modulation technique for radio over fiber
(RoF) in passive optical network (PON). A laser source of 1550 nm wavelength
was used with 100 km, 140 km
and 288 km single
mode fiber. In the OFDM-PON a passive optical splitter of ratio 1:2 is used to
connect two optical network units (ONUs). A 10 Gbits/sec transmission bit rate
is used to simulate the RoF-OFDM-PON system. The proposed system can provide a
flexible, cost effective and significant high data rate.
