PASSIVE OPTICAL NETWORK HAVING FEW-MODE FIBERS COUPLED TO MODE CONVERTERS

摘要

The invention relates to a method for managing a passive optical network, said passive optical network comprising at least one few-mode fiber (610) to centralize connections relative to several optical network units to a central office (500), wherein said central office (500) is provided with: - optical line terminations (521-524) to at least emit multiple bandwidths (» 1 , » 2 ), and - at least one mode converter (540) acting as a power splitter to multiplex said multiple bandwidths to different power modes, said different power modes being then provided to said at least one few-mode fiber (610).
