A symmetric bidirectional mode division multiplexing (MDM) based next generation passive optical network stage 2 (NGPON2) design is presented in this paper. Utilization of dual polarization quadrature phase shift keying (DP-QPSK) modulation scheme over hybrid free space optics (FSO)/fiber link indicates that the proposed design offers faithful 200 km fiber and 50 m FSO range at mode 0. Minimum received power of -18 dBm and maximum optical signal to noise ratio of 36 dB are achieved successfully. Also, the results indicate that DP-QPSK scheme allows better system performance than others schemes. Comparison of the proposed model indicates its superiority over other recent works.

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.
