研究目的
Investigating the influence of inter-channel nonlinear interference (ICNI) on the quality of transmission (QoT) estimation under flexible network configurations.
研究成果
The paper concludes that ICNI power increases as channel spacing increases, with the ICNI power at a channel spacing of 50 GHz being 3.6 dB higher than at 100 GHz. The Q factor is significantly affected by the modulation format of interfering channels, especially at higher powers.
研究不足
The study focuses on the influence of ICNI on QoT estimation under specific network configurations and does not cover all possible scenarios in elastic optical networks.
1：Experimental Design and Method Selection:
The study uses a modulation format dependent inter-channel nonlinearity calculation to analyze the influence of interfering channel modulation format, channel spacing, and optical power on QoT estimation.
2：Sample Selection and Data Sources:
Numerical results are obtained through a modulation format dependent EGN model.
3：List of Experimental Equipment and Materials:
The fiber links comprise standard single-mode fiber with specific parameters.
4：Experimental Procedures and Operational Workflow:
The study investigates the influence of interfering channel number and spacings on the ICNI of interfered channel and compares the influence of the interfering channels modulation format on ICNI power for different transmission distances.
5：Data Analysis Methods:
The Monte-Carlo integration method is adopted in calculation.
