Abstract:
An optical data transmission system, the system having a laser source, means for actively modelocking the laser source to simultaneously generate up to approximately 4 wavelength channels, the improvement comprising:means for simultaneously generating up to approximately 21 wavelength channels from the laser source;means for multiplexing the channels;means for optically amplifying the multiplexed channels; andan optical clock recovery means having:means for splitting data signals from the channels into a first data path, and a second data path of multiwavelength data;means for recovering optical clock pulses from the first path; andmeans for demultiplexing the optical clock pulses and the multiwavelength data from the second data path, wherein the multiplexer means and the optical amplifier means and the optical clock recovery means increases each of the modelocked wavelengths up to approximately 40 Gbits/s, and form an output having an aggregate rate of up to approximately 840 Gbits/sec.
