Abstract:

To overwhelm the issue of limited range of transmission span in traditional passive optical network (PON), we have proposed and designed a long-reach NGPON system, which supports 40Gbps Differential Quadrature Phase Shift Keying (DQPSK) downstream and 20Gbps Return-toZero On-off Keying (RZ-OOK) re-modulated upstream. After investigation of proposed design in simulation for 70 Km long-reach NG-PON, transmission performance has been evaluated through Bit error rate (BER) and received power on the basis of increasing splitter ratio for large number of customers. Simulative Results validate that proposed design is a feasible solution for high data rate transmission and long distance coverage with higher splitting ratio to accommodate large number of customers in Larger Metropolitan Area Networks (MANs).
