Etude des solutions d'accès optique exploitant une extension de portée

Abstract : In order to optimize the fiber network deployment, this thesis has the objective to study solutions to extend the reach of the access optical network. The first Chapter describes the optical access network context: from GPON (Gigabit Passive Optical Network) systems deployed today for FTTH (Fiber To The Home), to the Next Generation PON (NGPON) which is mainly driven by a rising bit rate as a mid or long term issue. Reach extension is also introduced in this chapter with the description of standardization works proposing the insertion of Extender Boxes in the optical access network. The second Chapter presents several solutions to extend the optical budget of a GPON system. Technical evaluations of Extender Boxes based on optical amplification or optoelectronic regeneration are made trough several configurations. Further studies regarding the economical aspect and expenditure of energy lead to other options for Extender Boxes such as wavelength multiplexing function and PON port duplicator. Finally, the third chapter deals with reach extension of NGPON systems. Optical amplification is evaluated over 10GPON, WDM PON and OFDM PON: SOA or EDFA are inserted on test platforms reproducing each type of networks.
