In this paper, a bidirectional 40/40Gbps time and wavelength division multiplexing-passive optical network (TWDM-PON) system employing 4-level quadrature amplitude modulation (4-QAM) orthogonal frequency division multiplexing (OFDM) modulation is proposed and analysed to ulfil the high bandwidth demand of next-generation access networks. The system has been analysed for variable distance, data rate and input power. The results show that the bidirectional 40/40 Gbps traffic can be transmitted successfully up to 200 km with an optimum input power of 16 dBm at 3.8×10-3 bit error rate (BER) using digital signal processing (DSP) unit. Also, the proposed system shows its superiority as compared to previous work.

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.
