Abstract

The idea of Radio over fiber (ROF) is integrated with Wavelength Division Multiplexed Passive Optical Network (WDM-PON) keeping in mind the end goal to exploit the benefits of high information rate and expanded versatility. In this paper, we propose a full duplex ROF WDM-PON framework utilizing Subcarrier multiplexing (SCM)/Amplitude Shift Keying (ASK) strategy. The proposed framework depends on wavelength re- modulation which makes utilization of bidirectional intelligent channel having the same wavelength for uplink and downlink. Recreation of the framework exhibits 1 Gbps uplink and downlink information for 17 channels. A limited separating of 0.4 nm is kept up between the channels to enhance the capacity. The execution of framework is controlled by examining the variation in Quality factor (Q-factor) component and Bit Error Rate (BER) when an optical fiber length and input power values changes. The proposed setup gives the acceptable value of Q-factor (8.91, 7.71 and 6.04) on the fiber length (10 km, 20 km and 30 km), respectively with a fixed input power of 5 dBm..
