Abstract
A method and network are provided for a reconfigurable optical sensor network. The method includes configuring, by a controller, the reconfigurable optical sensor network, including one or more reconfigurable optical space switches, for a type of sensor data. The method also includes generating sensor data in the type of sensor data with one or more of a plurality of bidirectional sensors. The method additionally includes sending the sensor data to one or more optical star couplers. The method further includes forwarding the sensor data from one of the one or more optical star couplers to the one of one or more reconfigurable optical space switches.
