TraceLogic Pro

Trace Logic

About this app

TraceLogic Pro is the complete fibre optic engineer's companion — built for field use, offline-first, and packed with the diagnostic tools you actually need on site.

OPEN SOR FILES INSTANTLY
Open .sor traces from any major OTDR (EXFO, Viavi, Anritsu, Yokogawa, FibreOptics) with full event detection, splice loss, reflectance, and total link budget. Inspect the raw curve, jump between events, and export reports — all without an internet connection.

GUIDED FAULT DIAGNOSIS
Walk through 25+ real-world fibre fault scenarios with a guided decision tree. Diagnose dirty connectors, ghost events, macro-bends, dead fibres, and high splice loss with the same logic experienced engineers use — at your fingertips, calmly, step by step.

BI-DIRECTIONAL CALCULATOR
The bi-directional splice loss calculator instantly averages A→B and B→A measurements to give you the true splice loss, with EXFO FastReporter-grade accuracy and a clear good / acceptable / investigate / re-splice verdict.

SMART FLAGS + CONFIDENCE ENGINE
Each trace gets a verdict-first banner, smart flags for the seven most common faults, and a confidence rating that tells you when to trust the result and when to re-test.

PROJECT MANAGEMENT
Group traces by project, cable, and fibre. Auto-match A→B and B→A directions. Visualise health at every level — from a single splice up to a multi-cable network.

TEAM DASHBOARD (COMPANY)
Invite your team, share projects across engineers, and see network health roll up across every site. Live KPIs, network maps, document hubs, and PDF report generation that matches FastReporter's level of detail.

OFFLINE-FIRST, EVERYWHERE
Designed for offshore platforms, underground installations, and remote sites with zero connectivity. Your traces, projects, diagnostics, and learning content all live on your device. The cloud is an enhancement, not a dependency.

LEARN AS YOU GO
The reference library and learning modules cover OTDR fundamentals, splice technique, fault classification, and best practice — searchable, structured, and gradeable with built-in quizzes.

What’s new

Calculator now accepts comma decimals (e.g. 1,5 km) alongside dots.
Bi-directional trace upload simplified: one uploader that auto-pairs A→B and B→A by direction and wavelength.
Plan info now accessible from the Account tab; subscription status auto-refreshes on focus.
Quiz answer fix for the subsea-to-topside splice scenario.
Stability and small UI improvements.
