By the non-linear Schr?dinger equation which satisfies the optical soliton propagation,according to the data of literature and the experiment,high order dispersion and non-linearity affect the orphan pulse transmission analyzed and obtained some meaningful conclusions:when the chirp,high-order chromatic dispersion and the fifth-order simultaneously existing,they can affect the pulse transmission characteristic very tremendous,and between these factors exist the mutual influence and the restriction relations.The numerical simulation indicated that when the parameter of the chirp,high-order chromatic dispersion and the fifth-order selected some value,they have the gain effect and the reshaping effect to the pulse.These conclusions obtained in this article has certain reference significance to the optical soliton communications′s practice process.
