Abstract:
1. An optical network device comprising: a plurality of optical lines to each carry a multiplexed optical signal; a first optical switch connected to the plurality of optical lines to select one of the plurality of optical lines for information generation related to dispersion characteristics of the selected optical line; a receiver connected to the first optical switch to generate dispersion information about the multiplexed optical signal carried on the selected optical line by performing optical/electrical conversion on a selected wavelength of the multiplexed optical signal, wherein the dispersion information includes bit error rate information about the multiplexed optical signal; and a memory device connected to the receiver to store the dispersion information about each of the plurality of multiplexed optical signals, wherein the memory device uses the stored dispersion information to reduce the amount of dispersion for each of the plurality of multiplexed optical signals.
