Paper Abstract

Optical access networks are developing to be large bandwidth, high capacity and long distance. The Hybrid Passive Optical Networks (HPONs) using Time Division Multiplexing (TDM) technology and Wavelength Division Multiplexing (WDM) technology are becoming representative technologies that will be employed in the next generation access network. A novel scheme of HPON system architecture based on the wavelength conversion technology is presented. The advantages and disadvantages of a variety of wavelength conversion technologies are contrastively analyzed, and a novel 1.25Gbps burst-mode Optical-Electrical-Optical Wavelength Converter (BM-OEOWC) used in the uplink channel of this HPON system is realized and designed. The receiver sensitivity of this Optical Wavelength Converter reaches -30dBm, and the dynamic range of the input optical power reaches up to 20dB. Theoretical analysis is presented to explain why Bit Error Rate (BER) would obviously increase if more ONUs are attached to this converter. An improved scheme is proposed at last.
