Abstract :
We report on the use of a novel all-fiber flat-top pulse shaping technique for improving performance and timing jitter tolerance of a switch made for 640-10 Gb/s signal demultiplexing. The jitter tolerance is increased to almost 30% of the one-bit time window, and an increase of the receiver sensitivity by 13 dB compared to a nonflat-top pulse is reported.
