A method for token-controlled data transmission includes receiving a token including transmission data specifying one of a plurality of data channels and a time window. A burst blocker is configured, based at least in part on the transmission data, for the selective communication of the specified data channel on an optical transmission medium having the plurality of data channels. The selective configuration of the burst blocker includes splitting the specified data channel from the plurality of data channels, configuring the burst blocker in a first configuration during a time other than the time window to rejoin the specified data channel with the plurality of data channels for transmission of the plurality of data channels toward a destination node, and configuring the burst blocker in a second configuration during the time window to block the specified data channel to prevent the transmission of the specified data channel.
