Title:
非ソリトン信号を光ファイバ伝送するシステムのための光再生方法及び装置
Document Type and Number:
Japanese Patent JP4105272
Kind Code:
B2
Abstract:
. The method for the regeneration of return-to-zero (RZ), non-soliton optical signals comprises an initial compression of the RZ signals into soliton type signals. There is a subsequent synchronous optical modulation of the soliton type signals, using a clock. The modulated soliton signals are finally decompressed into non-soliton. RZ signals. The compression process preferably includes a spectral or time processing of the optical coded signals, especially by spectral filtering, with amplification and propagation of the signals in a non-linear optical dispersing medium.
