A fiber optic transmitter comprising a digital driver adapted to adjust the crossing point of a digital base signal, an optical source adapted to receive the digital base signal and produce a frequency modulated optical signal, and an optical spectrum reshaper adapted to convert the frequency modulated optical signal to an amplitude modulated optical signal. A method for transmitting a signal, comprising: adjusting the crossing point of a digital base signal; providing the adjusted signal to an optical source to produce a frequency modulated optical signal; and providing the frequency modulated optical signal to an optical spectrum reshaper to convert the frequency modulated optical signal to an amplitude modulated optical signal.
A fiber optic transmitter comprising a digital driver configured to generate a digital base signal transitioning between high and low signal levels, the digital driver further configured to maintain a crossing point of the digital base signal at an offset signal level substantially different from a middle signal level located at 50% of a distance between the high and low signal levels;
A fiber optic transmitter comprising a digital driver adapted to adjust the crossing point of a digital base signal, a directly modulated semiconductor laser adapted to receiver the digital base signal and produce an optical signal, characterized in that:
A method for transmitting a signal, comprising:
