Passive optical networks with mixed bit rates by the use of an integer divider of a maximum data rate for the dynamic adaptation of bit rate in ongoing operation

摘要

The method involves providing a central node i.e. optical line terminal, that is connected to a set of end nodes and a set of subscriber stations (11). The central node is provided with a maximum data rate. The end nodes are arranged with another data rate in accordance with an integral divider. The integral divider is arranged with maximum data rate that is smaller or equal to maximum data rate of the central node. The central node and the end nodes are allowed to exchange information with specific velocity. The central node and the end nodes communicate with the integral divider. An independent claim is also included for a star-shaped network infrastructure.
