FTTH can be consisted with several types of topologies / technologies used.
Most common 3 patterns would be:
*Simple media converter. No sharing of a fiber end to end, at least
per wavelength.*Active Optical Network (active star). One or more 1:n star topology,
each of the stars are controlled by managed channel divider.
Upstream side of fibers are shared.*Passive Optical Network. One or more 1:n star topology,
in each of stars, signals are splitted into n downstream and
merged into 1 upstream using optical prism.
As all downstream fibers receive exactly the same signals,
each sides of all terminals need to be strictly synchronized
and each packet is needed to contain initiator and target
to determine the packet to be for /from which terminal.Basically, the latter, the cheaper.
And if the upstream terminal has no free connector, need to wait until any of them are freed or introduced additional terminal.
Active star has another bottleneck on supply chain, channel divider. This is (AFAIK) less common, thus, possibly hard to quickly obtain.

@olberger I routinely back stuff up through their interface but I bricked things so badly that I couldn’t access the admin via their graphical interface.
Figured it would be quicker to nuke everything and start over (than going through terminal).
That installation was basically 30 min old and I didn’t have anything important on it. Just a fresh install of Sharkey 😅

@garthbeagle Is that Apple Bob?

Avevo proprio bisogno di riposare. Ora potrei dedicarmi a qualcosa di creativo. Domani vorrei rimettere piede in cantofficina e riprendere tutte le cose lasciate in sospeso...

Amore e fusa...

@elena
Have you tried backing up and restoring ?
That kinda stuff may be worth having on your agenda some day ;-)

@oblomov abbiamo fatto lavori preparatori, prendendo il docker-compose della versione nuova e integrandolo con le impostazioni di quello in uso, l'upgrade finale è rimandato causa pioggia che ha fatto saltare il rendez-vouz tecnico.

@francescotoniolo ah peccato, spero sia solo una dimenticanza, e che se gli piacciono questi giochi trovi il tempo di scrivere anche solo un grazie 😉
