Scaling the system capacity and reach of a 10G-TDM-OCDM-PON system without an en/decoder at an ONU

To realize high scaling of a 10-Gbps-class optical access system, we propose and demonstrate two different long-reach hybrid multiplexing passive optical network (PON) systems. First, we demonstrate good scalability in the ultimate transmission distance over 100 km single-mode fiber without dispersion compensation of a 10G wavelength division multiplexing (WDM)-time division multiplexing (TDM)-optical code division multiplexing (OCDM) PON system. Second, we also demonstrate a 100 km 10G/1G-TDM-OCDM-PON system for the purpose of the scalability of the current mixed GE-PON and 10G-EPON system.
