Abstract :
This paper we have demonstrated a transmission system for perfect integration of ROF with centralised OFDM-PON based on an external modulator. The transmission performance of modulation based on OFDM-PON for next generation. The signal is generated by direct modulation of low bandwidth and cost effective implementation presented CW laser at 193.1 THz. We have experimentally demonstrated the downstream OFDM-PON transmission over 55 km single mode fiber also simulated through 1:2 splitters. After all for QAM and PSK modulation results are analyzed in time domain based on optical signal spectrum. And these analyzed results are compared with numerical result for QAM and PSK modulation scheme to distinguish.
