摘要：
Passive Optical Network is designed such that it meets the requirements of NG-PON. According to FSAN, the Time and Wave Length Division Multiplexing (TWDM) is chosen as the best solution to implement NG-PON. EDFA amplifier is used in the system to compensate the effects of degraded signal in both the directions upstream/Downstream (US/DS). It is observed that system can transmit over 40 Km SMF with acceptable BER. NG-PONs also remarkably improves increase in the users to 2400 downstream and 512 upstream. It is observed that with increase of link length the value of Q-factor decreases and there is increase in the BER. Capacity enhancement, high data rate and large bandwidth can be achieved by using advanced modulation formats between efficient techniques.
