Pulse shaping for optical fiber communication systems.
Fiber optics. ; Optical communications. ; Pulse circuits.
A fiber can transmit around 25 Tbit/s, but electronic signal processing today is performed at much slower speeds, usually 1-10 Gbit/s. To avoid this "bottleneck" in optical fiber communication systems, all signal processing will have to be done...
