Abstract
A link setup method for a wavelength-division-multiplexing passive optical network (WDM PON) system. The system includes a service providing device, a local node, and a plurality of subscriber devices. The link setup method includes assigning an initial wavelength for communication between the service providing device and a new subscriber device to be installed in the local node. The assigning of the initial wavelength may be performed as a part of process for activating the subscriber device, and this procedure may be performed between a physical layer of the service providing device and a physical layer of the new subscriber device.
