Coherent detection is a promising technique to compensate for the linear and non linear impairments of an optical communication link. Coherent optical receivers followed by Digital Signal Processing (DSP) facilitate in demodulating advanced modulation formats like Quadrature Amplitude Modulation (QAM ), providing an effective solution to upgrade optical backbone network. Orthogonal Frequency Division Modulation (OFDM) is being widely studied to implement scalable, dispersion compensated high speed optical networks. This work aims to design and analyze a spectrally efficient QAM OFDM opt ical network. In order to further boost the system capacity dual polarized signal has been investigated..

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.
