Performance Enhancement of 8 Channel WDM-RoF PON system at 80 Gbps data rate using Raman Amplifier (original) (raw)

The proliferation of smart phones, tablets Machine-to-machine (M2M) communications and the rapid emergence of the internet of things (IoT) based applications have raised demand of huge bandwidth. Services for applications like Image transfer, video streaming, as well as innovative cloud in real time demand wireless broadband access. To cater such demands wireless access schemes using Radio over Fibre (ROF) technology can be used faithfully. RoF is becoming matured technology in terms of security, reliability and coverage. Use of Raman amplifier can be done to mitigate limitations such electrical power attenuation, multipath fading and chromatic dispersion for comparatively long distances. In this paper we have proposed the design of WDM RoF PON link operated at 80 Gbps data rate which comprises 8 multiplexed channels with 100GHz channel spacing with PSK modulation technique. Due to their abundant bandwidth ROF networks are capable of supporting multiple RF subcarriers simultaneously. Performance of proposed system is evaluated in terms of Q factor and BER parameters which provides better insight into quality of received signals.
