Abstract

The invention provides a main optical channel power test method. The method includes the following steps that: WDM optical signals to be tested are scanned, so that the central wavelengths of optical signals in the WDM optical signals can be obtained; effective spectral widths occupied by the optical signals can be determined according to the central wavelengths of the optical signals in the WDM optical signals; and the main optical channel power of the WDM optical signals is tested according to the central wavelengths of the optical signals in the WDM optical signals and the determined effective spectral widths. Based on the same conception as above, the invention also provides a main optical channel power test apparatus. With the main optical channel power test apparatus adopted, main optical channel power measurement of multi-sub-carrier multiplexed super channel spectra of flexible spectrum intervals can be performed flexibly.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for testing the power of a main optical channel. Background technique [0002] With the rapid development of new Internet services, the demand for the capacity and bandwidth of optical fiber bearer network is increasing day by day. In the 100 Gbit After the optical communication system of / s (abbreviated as 100G) has matured and been commercialized on a large scale, the ultra-100G optical communication system represented by 400Gbit / s (abbreviated as 400G) has also begun to enter the stage of laboratory testing and trial commercialization. [0003] The ultra-100G multi-subcarrier multiplexing optical communication system aims to improve spectral efficiency and transmission distance, and introduces new technical features such as high-order modulation formats, multi-subcarrier multiplexing super channels, and flexible spectrum spacing at the physical layer...
