Title:
ＯＳＮＲスペクトル推定装置、ＯＳＮＲスペクトル推定方法およびプログラム
Document Type and Number:
Japanese Patent JP7155756
Kind Code:
B2
Abstract:
An OSNR spectrum estimation apparatus includes an OSNR estimation unit configured to cause an optical node to estimate an OSNR of a predetermined transmission line using a probe light of a predetermined wavelength in a predetermined number of wavelength channels, the predetermined number being less than the number of all wavelength channels; and an OSNR spectrum calculation unit configured to calculate an OSNR spectrum of all the wavelength channels from OSNRs of the predetermined number of wavelength channels measured by the optical node.
