A true digital twin for telecom & utility networks

MarlinDT is a true digital twin for telecom and utility networks — every cable, every fibre, every splice, and the live services riding on them. One source of truth, from survey to business intelligence, built on Esri. And behind it: the team operators call when the migration is too hard for anyone else.

One platform. Six processes.

Physical + active, integrated.

Millions of subscribers migrated.

Recognize this?

In the boardroom, everyone agrees the data is fine.

Then management leaves the room — and the real picture comes out. A two-year backlog of as-builts. The network scattered across spreadsheets, CAD, Visio, PDFs, KML, shapefiles, Oracle and SQL. A NOC that can’t answer “who’s affected?” without three phone calls. An automation roadmap quietly stalled by data nobody fully trusts.

It doesn’t have to work this way.

From a digital map to a digital twin

For decades, we digitized workflows. What we never truly digitized was the network itself.

Disconnected GIS, CAD, databases and spreadsheets leave operators without a trusted source of truth. During outages, that means slower decisions, longer repairs and unnecessary fieldwork.

A digital twin provides the foundation. Because in 2026, AI doesn’t need more data—it needs data it can trust.

Why model your network How we think about AI

Why operators choose MarlinDT?

Same capabilities as the systems you're replacing — with the architecture, openness and people they were never built for.

One source of truth

Survey, plan, design, build, operate and report all read and write to the same live model. No silos, no reconciliation, no surprises.

Physical + active, natively integrated

PNI and LNI in one platform mean true end-to-end root-cause and single-point-of-failure analysis across the passive and the active network — not two tools stitched together.

GIS as a tool, not a GIS tool

Built on Esri ArcGIS and purpose-built for telecom and utilities, so your whole organisation gains a geospatial powerhouse — not a generic map.

The team that gets it done

Software gets you most of the way. The last stretch — the messy legacy, the missing associations, the impossible deadline — is where our people come in. We’ve migrated millions of subscribers and never walked away from a project.

Four modules. One data model.
Add what you need.

PNI
Physical Network Inventory

From head-end to customer: every cable, fibre, splice and port, OSP to ISP.

LNI
Logical Network Inventory

The active network, mined automatically from the elements themselves — no manual entry.

MNI
Network Intelligence

Real-time, business-friendly KPIs and dashboards for leadership, planning and investors.

Data Toolbox

Migrate, clean, validate and monitor — get the data in and keep it trustworthy.

Physical and active. Finally in one place.

Most inventories see only the passive plant or only the active services — never both. MarlinDT links them. From the map view of your physical network, jump straight into the lightpaths and the customers riding them.

So when a cable is cut or a POP goes down, you see exactly who’s affected, how much redundancy you have left, and what to do — across the passive and active layers, in one click. That’s the difference between a map and a digital twin
