This records the result arrays, along with context information, from an Optical Time Domain Reflectometry (OTDR) run. The arrays will define the relative scattered power from the Rayleigh scattering vs distance along the fiber. The actual data values are recorded in a wellLog object, which is referenced in a subelement. The reason the OTDR test was run. The three main reasons are 'pre-installation', which is before the installation of the fiber; 'post-installation', which is used to validate a successful fiber installation; and 'DTS run', which is a quality check of the fiber prior to a DTS run. A fourth permitted value is 'other'. The dateTime of the run. A reference to the well log used to record the table of data. A pointer to the fiber connection node. If more than one node is available for a well/wellbore, this element is used to specify which node is connected to the instrument box. This name should correspond to the fiberEndPoint/name that is recorded in the installed system object. A general comment about the OTDR run. Unique identifier for the run.
