Abstract :
An upgradable broadcasting service enabled all-optical OFDM-PON architecture based on centralized comb source is proposed. Optical frequency comb generator based on a re-circulating frequency shifter for our OFDM-PON system is illustrated. The configuration employs only one light source to support 8 optical network units for downstream, upstream and broadcasting services.
