Domain Knowledge
Charter: Ground-up domain courses — the physics, architecture, and operations of the networks we model. Read these to understand what we are inventorying before you touch how we model it.
The platform is domain-agnostic, but the people building it are not allowed to be. These courses take you from first principles to the operational realities of each network we serve. They are full standalone lessons (built with the Vinxi design system) served alongside the Book.
Fiber / FTTx
The optical access network — from photons in glass to the GIS digital twin that inventories it. Start here if you are working on the fiber data model, splicing, or outside-plant topology.
