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.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
