FiberQ

An open-source QGIS plugin for designing fibre optic networks (FTTH/GPON/FTTx).
Repository vukovicvl/fiberq
Author Vladimir Vukovic
Licence GPL-3.0-or-later
Funding NLnet NGI0 Commons Fund
Tested on Qt5 and Qt6
Current version v1.4.0 — validation and reporting

What it does

It builds the physical picture of a fibre network on the map:

  • Route — the line cables follow
  • Poles, manholes, ducts — the supporting infrastructure
  • Cables — backbone / distribution / drop, underground or aerial
  • Elements — ODF, OTB, TB, TO, joint closures
  • Slack — terminal and mid span
  • Buildings — subscriber premises
  • Service areas — coverage polygons

And on top of that: validation, a bill of materials, export, publishing to PostGIS.

Where things are

  • Toolbar

    Every button and menu — what it does and how it translates.

  • Validation

    The 14 rules that check a project before handover.

  • Data model

    Layers, fields, fiberq_uuid and the length arithmetic.

Installing

From the QGIS plugin manager, or straight from the repository. Qt Linguist, which the translation work needs, already ships with QGIS:

C:\Program Files\QGIS 3.44.5\apps\Qt5\bin\linguist.exe
C:\Program Files\QGIS 4.2.0\apps\qt6\bin\linguist.exe

Language handling

FiberQ has its own language setting, independent of QGIS. The logic lives in fiberq/i18n/__init__.py and resolves in this order:

  1. FiberQ/lang — the plugin's own language selector (wins)
  2. locale/userLocale — the QGIS-wide language
  3. The system locale

Why it works this way

The code comment explains it: a user may want FiberQ in one language and QGIS in another — common where the local fibre vocabulary differs from the language someone prefers for the rest of their GIS.

A language change takes effect after QGIS restarts — the catalogue is installed once, when the plugin loads.

ka is not in the list yet

_LANGUAGE_NAMES has no Georgian entry, so the language menu would show ka instead of ქართული. The code tolerates this deliberately (an unknown code falls back to itself, so the menu never breaks), but one line fixes it:

'ka': 'ქართული',
