We develop a theory of the pulse shepherding effect that allows simultaneous propagation of pulses in parallel bit slots by binding them into a multicomponent BPW soliton. We describe families of the BPW solitons and bifurcation cascades in a system of N incoherently coupled nonlinear Schrödinger equations that model the multichannel multiwavelength transmission in a single-mode optical fiber. We demonstrate high robustness of the composite BPW solitons, due to their underlying linear stability, to a moderate pulse walkoff.Keywords: Bifurcation (mathematics); Computer networks; Laser pulses; Light propagation; Mathematical models; Nonlinear equations; Optical links; Single mode fibers; Solitons; Wavelength division multiplexing; Bit parallel pulse transmission; Multichannel wavelengt Bit-parallel pulse transmission; Optical solitons; Pulse walkoff; Soliton bifurcation diagram; Wavelength-division multiplexing200210.1109/JSTQE.2002.10163622015-12-12
