Solutions for Budget Increase for the Next Generation Optical Access Network

After a presentation of the France Telecom Group's optical deployment project based on available technology, our interest for the Next Generation Passive Optical Network is described. With the need for increased bit rate, splitting ratio, as well as the reach extension, more optical budget will be required. Solutions for optical amplification in the target architectures which can ensure the evolution of the access network are presented. These solutions are compared in different schemes and the budget increase for the upgrade of Gigabit PON (GPON) system is deduced.
