"Chirping" will convert a short-duration wideband pulse into a signal that has a smaller peak-to-average value (and back again), but it won't time-compress an arbitrary signal in any recoverable way. If you try to AM the chirped pulse, the compensation fiber will turn this into a narrow waveform in which the actual information is encoded in the "noise" that comes before and after the main pulse. Not at all useful for TDM. | |
