Architecture¶
How the signal gets from the head end to the subscriber, and what each stretch is called.

The three cable classes¶
In FiberQ's menu these three sit side by side, twice — once under Underground and once under Aerial. That is why Georgian renders all three in the same grammatical form, as adjectives, so the list reads evenly.
| # | English | Georgian | Meaning |
|---|---|---|---|
| 1 | Backbone |
მაგისტრალური | Transport cable between the main network nodes |
| 2 | Distribution |
გამანაწილებელი | From a backbone node out to the street distribution points |
| 3 | Drop |
აბონენტური | From a distribution point to one subscriber's building |
Drop is a noun
Drop here is a noun — the drop cable, the subscriber cable. Not the verb.
The catalogue flags this separately, because machine translation reads it as a verb
almost every time.
The Georgian noun for the concept is მაგისტრალი; the menu uses the adjective
მაგისტრალური so all three classes line up in one series.
The two installation methods¶
| English | Georgian | Meaning |
|---|---|---|
Underground |
მიწისქვეშა | In a duct or a trench, below ground |
Aerial |
საჰაერო | Strung overhead on poles |
საჰაერო ხაზი ("overhead line") is the established Georgian collocation, which is why
that adjective was chosen.
What happens along the route¶
A cable seldom runs uninterrupted from A to B. Along the way:
- Joint closures — fibres are spliced, or some are branched off
- Slack — coiled spare cable for future splicing (in detail)
- Latent elements — passive elements recorded along the cable
- Branches (
Branch) — points where cables meet or split
Branch is not a company branch or a git branch
FiberQ's Branch info button shows how many cables, of which types and capacities,
meet at the point you click. French: dérivation.
What FiberQ does with all this¶
The plugin builds this structure on the map: the route is a line, elements are points, buildings are polygons, and each has its own layer and attributes.
