A Novel Hybrid 10G/1G Coexisted TDM-PON Using Central Office Controlled Reflective Transmitters for Low-Cost Upstream 10G Services

A novel hybrid 10 G/1 G coexisted TDM-PON based on reflective ONUs is proposed and experimentally demonstrated. 10-Gb/s upstream is successfully achieved by 4 piped 2.5-Gb/s sub-units in the ONU with negligible power penalty less than 0.2 dB.
