Abstract: Optical fiber communication system is rapidly developing towards the direction of ultra-high speed, large capacity, and dynamic aspects. New dimensions and multiplexing methods, as well as more complex architecture will be introduced to meet these requirements. However, they also pose a huge challenge to the reliable and safe operation and management of transmission networks. The physical layer parameter monitoring technique which can monitor and warn the impairments of optical fiber transmission networks would provide information source and management basis for adaptive compensation, quality of transmission (QoT) and network resource optimization. Therefore, it would be valuable, in both scientific and social point of view, to enhance the reliability and safety of operation and management. Research highlights of chromatic dispersion monitoring, nonlinearity monitoring and modulation format monitoring are first reviewed, then followed by the discussion about the trends of performance monitoring technology for multi-dimensional optical fiber communication systems. It is concluded that the future performance monitoring will be characterized as precise measurement, functionality integration, intelligent processing and simultaneous multi-parameter monitoring.

Key words: optical performance monitoring, chromatic dispersion monitoring, nonlinearity monitoring, modulation format monitoring
