Embodiment Construction
[0019] When the optical data signal is sufficiently degraded, re-amplification, re-timing and re-shaping of the optical pulse is required; this is referred to as "3R regeneration". To avoid the cost and complexity of photoelectric conversion, it is advantageous to perform 3R regeneration entirely within the optical domain, thereby eliminating the electron regeneration bottleneck. By combining the two unique capabilities of TOAD - high bandwidth sampling and precise pulse shaping, the present invention provides an all-optical 3R regenerator that completely removes any timing jitter in the signal, as well as amplifies and reshapes the signal to remove Any waveform distortion.
[0020] FIG. 1 is a block diagram of an exemplary system 100 that includes one embodiment of the present invention. The optical data signal 11 represents the signal applied to the transmission line 101 . After a certain distance, the data signal 11 degenerates so that the corresponding signal at the end ...
