Fiber Network Planning Engine
FiberCAD
Automated fiber network design that turns addresses into construction-ready plans in minutes, not weeks. Standards-compliant. Integrity-verified. LLM-assisted.
10x
Faster than manual CAD
100%
Standards-validated output
The Problem
Billions in BEAD funding. Not enough engineers to design the networks.
Today's Workflow
- Manual CAD design — experienced designer draws every conduit, splitter, and handhole by hand in AutoCAD
- 16-step process — from EOP linework to final QC, each step requires domain expertise
- 3-GIS costs $50K-$500K/year — plus Esri licensing at $5K-$15K per seat, plus 6-18 month deployment
- Talent bottleneck — takes months to train a designer, years to build judgment for optimization
- QC is manual — 17-step review checklist performed by a human on PDF output
FiberCAD
- Automated planning — feed in an area boundary, get a complete network design with splitters, conduit, and equipment
- Standards built-in — design rules are the software, not a PDF that humans interpret
- No Esri dependency — open-source GIS stack, cloud-native, zero vendor lock-in
- LLM-assisted review — AI evaluates trade-offs and suggests optimizations that normally require senior engineers
- Self-validating — every design is checked against standards before output, with a cryptographic integrity chain
How It Works
Six layers of graduated enrichment, from raw addresses to construction-ready output.
L0
Input
Address list or area boundary
L1
GIS Data
Buildings, roads, parcels from OSM
L2
Topology
Boundary groups, splitter tree
L3
Physical
Conduit routes, equipment
L4
Compliance
Standards validation
L5
Artifacts
DXF, BOM, reports
Competitive Positioning
Not another GIS tool. A design automation engine with built-in intelligence.

Key Differentiators
Layered Data Architecture
Every design layer is independently versioned, cryptographically signed, and auditable. Change one algorithm, regenerate downstream layers without losing upstream data. Full provenance from raw addresses to construction drawings.
Baremetal Tool Layer
Purpose-built tools for spatial queries, validation, and design analysis. The LLM never processes raw geometry — it calls deterministic tools and reasons about structured summaries. Reliable, fast, and token-efficient.
Domain-Expert Built
Built by fiber designers who know what a midsheath splice is, why bore pits cannot be in driveways, and why T-connections are not permitted. The standards document IS the software, not a reference PDF.
Rust-Ready Architecture
Pure domain logic with no framework coupling. Designed for migration to Rust for production performance. The Python MVP proves the algorithms; the Rust port makes them fast.
