In the future all-optical network controlled by generalized multiprotocol label switching (GMPLS), the wavelength path between end nodes will change dynamically. This inevitably means that the fiber parameters along the wavelength path will also vary. This variation in fiber parameters influences the signal quality of high-speed-transmission system (bit rates over 40 Gb/s). Therefore, at a path setup,...
We have succeeded field trial of GMPLS-based 40-Gbit/s wavelength path protection by photonic crossconnect. An automatic chromatic dispersion compensator was successfully applied to maintain the quality of a signal after protection operation.
