An optical transmitter for transmitting signals with high data rates, an optical transmission system and a method therefor

摘要

The invention concerns an optical transmitter (OT) for transmitting signals with high data rates, comprising at least one optical signal source for generating a return-to-zero like pulse signal, wherein further a conversion filter (CF) at the output of the optical transmitter (OT) is comprised and wherein the conversion filter (CF) shows filter means for generating an optical output signal (SO) with broadened pulses for reducing the use of spectral bandwidth, as well as an optical transmission system and a method therefor.
