Being the manner which forms PSD of the FTTN descending signal from deisutabasosu in order to achieve FTTN (the fiber to the node) descends and PSD of the signal (power spectral density) descent PSD

摘要

PROBLEM TO BE SOLVED: To provide a method for shaping PSD (Power Spectrum Density) of an FTTN (Fiber-To-The-Node) downstream signal from a disturber source to achieve spectral compatibility at an FTTN downstream victim with a downstream PSD from a reference source.;SOLUTION: The method includes receiving the downstream PSD from the reference source 116. The method further includes receiving an unshaped downstream PSD from the disturber source 104. The method further includes shaping the PSD of the FTTN downstream signal to have a substantially equivalent FEXT (Far-End Cross-Talk) into the FTTN downstream victim 108 as the downstream PSD from the reference source.;COPYRIGHT: (C)2008,JPO&INPIT
