Abstract:
Objective In order to build smart cities and fulfill the communication requirements of smart grids, Costa Rica needs broadband reliable communication networks.
Method Using FTTX architecture, GPON technology to build broadband access level fiber network.
Results Comprehensively utilizing pipe trench and tower resources of power Grid company, using GPON, multi-level light splitter and other technologies to build an ODN fiber network, which covers over 120,000 users of Heredia province, Costa Rica, fulfill the high-speed broadband communication needs of smart city and smart grid.
Conclusion Those technologies and the planing methods used in the build of an intelligent broadband communication network in Costa Rica can provide a good reference for the development of Chinese Smart Grid.
