OpenOTDR

What is OpenOTDR?

OpenOTDR is a revolutionary open-source OTDR (Optical Time Domain Reflectometer) reporting and analysis platform that’s bringing fiber network management into the 21st century. OpenOTDR makes building OTDR Reports, Localising Faults, and Sharing Results easy, replacing outdated PDF-based workflows that have plagued the industry since the 1990s.

Why Fiber engineers need OpenOTDR now

The Problem: Dark Fibre Network operators are still communicating with suppliers, field technicians, and customers via PDFs! No wonder it can take 30–45 days to deploy new connections and repair broken ones.

The Solution: OpenOTDR provides a modern, intelligent platform that:

• Eliminates PDF Hell - No more static reports that look like they’re from the 90s
• Accelerates Deployment - Cut deployment times from 30-45 days to days
• Enhances Fault Detection - AI-powered analysis identifies bends, breaks, splices, and anomalies automatically
• Integrates Everything - Combines OTDR traces with GIS data for precise fault localization

Game-Changing Features for Field Engineers

Multi-Wavelength Analysis

Load and compare traces at multiple wavelengths (850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm) to identify issues invisible in single-wavelength tests. Instantly spot macro-bends when wavelengths diverge - something PDF reports completely miss.

GIS Integration & Mapping

Load GIS map path data and Map SOR trace to GIS path for precise physical fault location. No more guessing where that 3.2km splice actually is on your route.

Project-Based Management

• Create and Manage tests in Projects
• Load SOR trace data
• Label features in trace data
• Export/Import Projects

Cross-Platform Availability

Coming Soon to iOS, Android, Mac, Windows, and Linux! Work on any device, anywhere - from field tablets to office workstations.
