Abstract:
An optical transmitter for amplifying a plurality of input signals operating over a predetermined wavelength range of &lgr;1-&lgr;N, the system comprisingat least one optical pump source for supplying at least one RF-signature modulated Raman pump signal, said at least one optical pump source comprising an element for providing a continuous wave (CW) optical pump signal; a radio frequency (RF) electrical signal generator; a modulator; and a unique pump signature element, the unique pump signal element being used with the RF electrical signal output from the RF signal generator and applied as an electrical input to the modulator, wherein the CW optical pump signal is applied as an optical input to the modulator, the output of the modulator comprising the RF-signature-modulated Raman pump signal.
