13.2.2 Challenges with DTS Data

Extensive use of the previous PRODML schema for DTS revealed the following areas requiring enhancements, which were first made in version 1.3.

• Data schema provided definitions for describing a fiber installation but more detailed information would be desired.
• A clearer distinction was needed between ‘raw trace’ measurements obtained from the fiber versus derived ‘log-like’ curve data that is eventually used for interpretation and analysis.
• Provision of a mechanism to label data with ‘versions’ was needed, in order to accommodate diverse business workflows that involve the use of DTS data.
• It would be useful to include placeholders for annotations and contextual data to aid subject matter experts troubleshoot any issues related to the DTS measurements.
