This is normally generated by biasing the optical modulator in such a way that the carriers passing through the two parallel paths of an interferometric m odulator have a π phase shift difference with each other. Thus, the carrier at the center frequency is suppressed, but the sidebands of the modulated signals remain unchanged. In PSK, the phase of the lightwave carrier is changed to represent the information. The phase in this context is the shift of the angle at the phasor vector initial position at which the sinusoidal carrier starts.
However, challenges due to environmental effects still remain to be resolved. The fundamental issues of soliton transmission are described. Temporal imaging for the refocusing of dispersive pulse sequences is also outlined. This temporal imaging is also used to minimize the jittering of soliton pulses due to noise generated from cascade optical amplifiers. 12) as follows. In this edition, Chapter 2 introduces optical fibers as the transmission medium for long-haul, metro, and access optical networks.
