Elements¶
In FiberQ an element means a passive optical device — ODF, OTB, TB, TO, patch panel, joint closure. It is not an "object" in the GIS sense.
Acronyms stay in Latin script
ODF, OTB, TO and TB stay in Latin script in the Georgian translation too, for
two reasons: that is how the field writes them, and ODF doubles as a layer name in
the code. Only the qualifying word is translated — Indoor OTB → შიდა OTB.

ODF — Optical Distribution Frame¶
The passive frame at the head end where feeder fibres terminate.
The network's starting point, where the operator's active equipment meets the fibre plant.
- Georgian:
ODF(acronym kept) - In FiberQ:
Place ODF→ODF-ის განთავსება; a layer of the same name exists - Source:
<extracomment>— "the passive frame at the head end where feeder fibres terminate"
Patch panel¶
The rack panel holding patch connections.
Its scope partly overlaps ODF, which the maintainer notes explicitly. The two must stay clearly distinct in Georgian.
- Georgian:
პაჩ-პანელი - Rejected:
კომუტაციური პანელი— more formal, less recognised in the field - Source:
<extracomment>— "the rack panel holding patch connections. Its scope overlaps ODF"
OTB — Optical Termination Box¶
The distribution point from which drop cables run out. Three variants by mounting location:
| English | Georgian | Where it sits |
|---|---|---|
Indoor OTB |
შიდა OTB |
Inside a building |
Outdoor OTB |
გარე OTB |
Outside, on a wall or façade |
Pole OTB |
ბოძის OTB |
On a pole |
Pole OTB is one element
It does not mean "a pole and an OTB" — it is a single element, an OTB mounted on a
pole. Serbian catalogue: OD ormar na stubu.
TB — Terminal Box¶
The Serbian backend name is ZOK (Zavrsna opticka kutija).
- Georgian:
TB(acronym kept — Georgian has no established equivalent)
TO — Termination Outlet¶
The subscriber-side optical outlet — the last element before the customer's equipment.
TO is an acronym, not the English preposition
The maintainer flags this trap separately. Place TO means "place a TO", not
"place something to somewhere". Both machine translation and human translators
misread this string.
Four variants:
| English | Georgian | Where it sits |
|---|---|---|
Indoor TO |
შიდა TO |
Inside a building |
Outdoor TO |
გარე TO |
Outside |
Pole TO |
ბოძის TO |
On a pole |
Joint Closure TO |
TO მუფტაში |
Inside a joint closure |
Joint Closure TO is a TO housed inside a joint closure — one element, not two.
Serbian: TO Izvod u nastavku.
Joint closure¶
The splice enclosure out on the route.
- Georgian:
ოპტიკური მუფტა, short formმუფტა - Other languages: fr
BPE, srnastavak - In FiberQ:
Place Joint Closure→მუფტის განთავსება
მუფტა is universally used in Georgian cable practice, which is why it was chosen over
any descriptive alternative.
Latent element¶
A passive element sitting on a cable's path at a recorded distance along it — stored as data, not drawn as a separate map feature.
This term looked opaque to me at first and I asked the maintainer about it — but the answer was already in the catalogue:
In FiberQ a latent element is a passive optical element (joint closure, ODF, OTB, termination box) that sits ON a cable's path at a recorded distance along it, between the cable's two endpoints — recorded as data, not drawn as a separate map feature. "latent" = intermediate/pass-through, NOT "faulty", "hidden bug" or "dormant".
- Georgian:
შუალედური ელემენტი - "Latent" is not faulty, hidden or dormant — it means intermediate / pass-through
What this page taught me¶
The <extracomment> notes are not supplementary information — they are a primary
source. Twice the "logical" translation from the English alone would have been entirely
wrong (Object, TO), and once I asked a question whose answer was already written down
(latent elements). Notes first, then translate.
