Optical beat interference-tolerant 60-km WDM/SCM-PON link based on reflective-SOA using amplified spontaneous emission and wavelength conversion

摘要

An optical beat interference (OBI)-resistant 60-km wavelength division multiplexed/subcarrier multiplexing-passive optical network (WDM/SCM-PON) is proposed. This scheme disperses OBI-noises using broadband amplified spontaneous emission (ASE)-light as an optical source for optical network unit. An uplink transmission is executed using a cross gain modulated light by ASE source with data in a local exchange. Error free transmissions of up and downlink are experimentally accomplished after 60-km optical transmission. The impact of Rayleigh backscattering noise on 100-Mb/s uplink signal is also investigated.
