MarlinDT Webinar - finding root-cause from OSP to ISP and OTDRs

Join our new MarlinDT webinar on 30 June — a quick tour through a real root-cause analysis.

Published at 25 June 2026 door Liesbeth De Ryck

It’s a short, practical tour — not a slideware pitch.

Luc De Heyn (CCO, Merkator) opens with who we are and where MarlinDT is heading,

Wouter Deleu (Customer Success Manager, MarlinDT) takes over for the product walkthrough.

A customer calls. Their connection is down. The clock starts.

To dispatch the right team to the right manhole — not three of them to the wrong ones — you need to answer a deceptively simple question fast: where exactly is the fault?

And the honest answer depends entirely on the state of your network inventory. Is it accurate? Complete? Up to date? Or does the truth live half in GIS, half in spreadsheets, with a CAD export and a couple of PDFs filling the gaps?

Tuesday 30 June

That scenario is the spine of a new webinar for MarlinDT, the digital twin for telecom and utility networks built by Merkator Group on Esri ArcGIS.

We’re running it live on Tuesday 30 June — and if you can’t make it, register anyway and we’ll send you the recording.

What you'll see in the tour?

We start from a real operational situation — a customer's connection is down — and work the root cause the way an operator actually would, using an OTDR measurement to pinpoint the exact fault location before anyone is dispatched. Along the way we move:

From the POP all the way to the customer

OSP and ISP, including the patching and splicing

MarlinDT Web and MarlinDT Desktop on ArcGIS Pro, so you can see how the field and the design office work off the same single source of truth.

And let’s continue in person.

We’ll be at the

Esri User Conference in San Diego, July 13–17, 2026 — booth 132.

If network inventory is on your mind — whether that’s data quality, migration, or operating a true digital twin — come find us. We’d rather talk about your specific challenge than give you another demo.
