Abstract
The symmetric 80 Gbps TWDM –PON is tested for non-return to zero (NRZ), return to zero (RZ), carrier suppressed return
to zero (CSRZ), and duobinary modulation formats for PIN and Avalanche photodiodes (APD). To improve the power
budget the distributed RAMAN amplification provides gain. The proposed 80 Gbps TWDM PON system supports a reach of
20km fiber with a 44.5dB power budget for duobinary modulation format and APD photodiode receiver utilizing forward error
correction (FEC) and 40.5 dB without FEC. The system serves 1024 optical network units (ONUs) in compliance with the
international telecommunication union-telecommunication (ITU-T) recommendation G.989.2.
Keywords
