A DAS acquisition system consists of a pairing of an optical path and a DAS instrument box, which are used to acquire DAS measurements. Because there are several ways in which an optical path and a DAS instrument box can be combined to make measurements, the DAS Acquisition object contains a reference to a path and a box from which the measurement was generated. This pairing of fiber optical path and DAS instrument box is known as a DAS Installed System. For examples of the combinations of Optical Path and Instrument Box which can be represented, see 14.5 Defining the Distributed Sensing Installed System .
