Abstract

Here 400 Gbps downlink Coherent Passive Optical Network (CPON) transmission has been demonstrated over 81 km of Standard Single Mode Fiber (SSMF) using Dual Polarization-16-Quadrature Amplitude Modulation at the central office with Digital Signal Processing (DSP) at the Optical Network Unit (ONU) and 1:64 power split at Remote Node. Adaptive DSP is employed at ONU to compensate the linear impairments caused by 400Gbps optical signal transmission over 81 km SSMF. The results obtained by simulation indicate that the proposed 400Gbps downlink transmission of CPON is practicable. The proposed high speed CPON may be exercised for the realization of the Next-Generation PONs..
