Abstract
This paper proposes and experimentally demonstrates a novel adaptive coded spreading (ACS) orthogonal frequency division multiplexing (OFDM) signal for dynamic distributed optical ring-based access network. The wavelength can be assigned to different remote nodes (RNs) according to the traffic demand of optical network unit (ONU). The ACS can provide dynamic spreading gain to different signals according to the split ratio or transmission length, which offers flexible power budget for the network. A 10Ã13.12Â Gb/s OFDM access with ACS is successfully demonstrated over two RNs and 120Â km transmission in the experiment. The demonstrated method may be viewed as one promising for future optical metro access network.
