This page provides an introduction to the Open Fibre Data Standard (OFDS), the reasons for using it and what OFDS data looks like.

What is the Open Fibre Data Standard?

The OFDS is a data standard for the publication of open fibre data. It describes what data to publish about fibre optic networks in order to meet a range of use cases and how to structure and format that data for publication and use.

The OFDS provides:

  • A common structured data model, including a schema, codelists, definitions and rules that need to be followed.

  • Publication formats to meet a range of use cases.

  • Guidance and tooling to support the publication and use of data

The OFDS covers the location of fibre infrastructure and the technical and administrative attributes of fibre infrastructure.

Why use the Open Fibre Data Standard?

Data standards resolve ambiguity by defining the structure and meaning of data. Standardised data is easier for people and systems to interpret than non-standardised data:

  • Without standards, data users or intermediaries have to do the hard work of making sense of different datasets and developing dataset-specific methodologies and tools.

  • With standards, users have access to information about the structure and meaning of data and can develop reusable tools and methodologies that can be applied to many different datasets.

Standardisation in the fibre context

The supply-side research identified a variety of units and notations for specifying the capacity of a fibre-optic span: Mbps, Gbps, STM notation and E-carrier notation. This lack of standardisation presents a challenge to users who want to compare the capacity of different spans and networks.

Since all of the above units can be converted into Gbps, OFDS requires that publishers specify span capacity in Gbps. This approach places the effort of conversion onto the data publisher, where it only needs to happen once, rather than onto data users, each of whom would need to convert the data if it were not standardised.

Standards can also ensure that key information is included in a dataset. If data owners do not share key information in their data, then users need to negotiate with each data owner individually.

In addition to publishing the locations of fibre network infrastructure, using the OFDS to publish data on the technical and administrative attributes of infrastructure helps to ensure that your data meets the needs of a range of users. For example, publishing data on the organisations that own and operate infrastructure can help operators and regulators to understand the true extent and resilience of fibre networks.

What does OFDS data look like?

To meet the needs of different users, OFDS data can be published in three formats: JSON, GeoJSON and CSV. The tabs below provide examples of OFDS data in each format:

The following example shows OFDS data containing a single network in JSON format:
