Abstract
We show analytically that if the response of a signal-reshaping processor
is slower than (or comparable to) the time scale of variations of the temporal
profile of the input signal, then such a processor necessarily degrades the
signal's bit error rate (BER). Here, the BER comparison is made for the cases
where the receiver is placed immediately before and immediately after the
processor. As primary examples of such processors, we consider all-optical
2R (reamplification and reshaping) regenerators, but also mention that the
aforementioned BER degradation can occur in wavelength converters and electronic
components of the receiver.
