Link between buildings over public land
The operator’s later cross-connects eat your budget after handover, which is why the acceptance measurement matters.

The problem
What makes it hard
Two buildings never share an earth potential. And the cable passes ground that somebody else owns and can dig in.
Two things are usually missed. The fiber is leased, which means it is measured by somebody else, with somebody else’s reference and somebody else’s conditions — ask for an OTDR record and a two-way attenuation measurement at handover, not a datasheet. And the ODF is usually not yours: every time the operator re-patches in their own frame, connector pairs are added to your budget without you being told. Size for that.
How it is built
Galvanic barrier and cross-connect inside the site
Where the isolation boundary sits is a design decision, not an installation detail.

Environments
Environments with the same problem
The technology is the same; the buying process usually is not.
- Railway signalling installationVibration and a 40-year installation lifetime set the requirements, not the data rate.
- Substation with teleprotectionDelay and channel asymmetry decide whether the protection trips correctly — the link is part of the protection scheme, not a service to it.
- Wind farmLong loops and lightning exposure, with maintenance access measured in hours of travel.
- Vehicle and vessel installationThe rugged data diodes carry 810G and 461 data; no converter, extender or switch in the catalogue does.
