ALTERNATE PHASE MODULATION FOR NON-SOLITON OPTICAL RZ TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To reduce the effects of non-linear interaction between adjacent pulses in an optical fiber transmission system having non-soliton RZ signals.;SOLUTION: The phase difference between the end of one pulse and the beginning of the adjacent pulse is assumed to be in the range from 2π/3 to 4π/3. The invention is implemented by inverting the phase of each new pulse sent, or varying the phase within each pulse.;COPYRIGHT: (C)2012,JPO&INPIT
