Next Generation Access Network (NGAN) Planning – FTTX/GPON
Course Overview
The development of optical access network (NGAN – Next Generation Access Network) can be implemented with different architectures (FTTx): with fiber links up to the cabinet (FTTC) or to the building (FTTB), or directly to the home (FTTH). Each solution, moreover, can be made with different topologies and technologies: point-to-multipoint (P2MP) with PON systems or point-to-point (P2P) with ethernet systems.
The course describes the different architectures, highlighting the advantages and disadvantages of various solutions. The key criteria of optical distribution network (ODN) planning, designing, and construction are explored and some case studies are proposed. The main guidelines of network operation and maintenance are described.
Target Audience
This course addresses the needs of telecommunications operators involved in the development and management of NGAN networks. It is suitable for network engineers and managers.
