ALTERNATE PHASE MODULATION FOR NON-SOLITON OPTICAL RZ TRANSMISSION

摘要

The invention relates to non-soliton RZ signal fiber optic transmission systems. To reduce the effects of non-linear interaction between adjacent pulses, it proposes that the phase difference between the end of one pulse and the beginning of the adjacent pulse be in the range from 2pi/3 to 4pi/3. The invention can be implemented by inverting the phase of each new pulse sent or by varying the phase within each pulse.
