Title:
波長分散測定方法及び装置
Document Type and Number:
Japanese Patent JP4356432
Kind Code:
B2
Abstract:
A test signal light intensity-modulated with a test data is generated and enters the optical transmission line. An extractor extracts the first and second optical components from the test signal light output from the optical transmission line, the first and second optical components composed of any one of a main signal light component, an upper sideband component, and/or a lower sideband component. A time difference measuring apparatus measures a time difference between the first and second optical components. A converter converts the measured time difference into a chromatic dispersion value.
