In order to advantageously weld a pre-mounted connector-plug part to an optical waveguide cable, the connector-plug part is provided with a pin holder receiving a connector-plug pin on a pin receiving section. The system comprises a sensor, a divisor processing unit, a reference signal generator, and a print trigger signal generator. For a network configuration, the technique uses as input a network-level packet trace of an application’s communication and extracts from it a set of features. Advantageously, each core section is provided with a closed end portion laterally spaced from the center of the hander for defining a maximum distance along which the plurality of arms can be transferred. In addition, at least one of the components in the infrastructure is controlled based upon the aggregated exergy loss values.
