| Abstract: | Adaptive dispersion compensation is one of the core technologies of ultrahigh rate fiber-optic communication networks and dynamic on-line monitoring on optical signal dispersion is the key to adaptive dispersion compensation. In this paper, we systematically review the study on dispersion monitoring technologies and its present status of development and analyze and compare their mechanisms, features and implementations. Above all, we put emphasis on introducing the all-optical and digital coherent detection-based dispersion monitoring technologies and discuss the tendency of their future development. |
