A novel OFSK transmitter using phase modulator-embedded optical loop mirror and carrier suppression modulation is proposed and experimentally demonstrated. Only one laser source is needed and its structure is simple for potential integration.
In this paper, we propose a novel polarization-assisted scheme for flexible multicast overlay in a WDM-PON, which supports both point-to-point (P2P) downstream and upstream data delivery. With our proposed wavelength assignment and routing schemes, the system performance is greatly improved. No additional dedicated light source for the multicast data is needed. We have experimentally demonstrated...
We propose a novel wavelength-division-multiplexed passive optical network which supports simultaneous delivery of 10-Gb/s point-to-point downstream and upstream data as well as 10-Gb/s downstream multicast data. The multicast overlay control is achieved by a polarization-assisted scheme at the optical line terminal (OLT). A separate lightpath is provided for the downstream multicast differential...
