Abstract
This paper experimentally demonstrates a novel dynamic λ-OFDMA architecture with selective differential phase shift keying (DPSK) overlaid and colorless optical network unit (ONU). The wavelength can be dynamically assigned to the splitter node in demand through a group of optical switches. Multicast control is realized through an alternative local oscillator at the optical line terminal (OLT). The 10-Gb/s × 4-channel 16QAM-OFDM unicast signal with 2.5-Gb/s DPSK overlaid and 1.25-Gb/s upstream signal have been transmitted over 25-km fiber successfully.
