A data connection switching unit is provided for use in an optical communication network, as well as an optical communication method and an optical communication network, in which, via a number of interconnected network node devices of an optical transport network, data is transferred to a second transceiver via a first data connection via optical signals, wherein a data connection switching unit is connected between the first transceiver and one of the network node devices, which independently instigates the setting up of a second data connection between first and second transceivers by virtue of the fact that it sends a data connection setup signaling signal to the corresponding network node device in which information referring to the desired course of the second data connection is included.
