Upload your OTDR .sor trace. We convert the fault distance into a GPS coordinate and street address, plotted on satellite imagery with your documented splice case locations. No guesswork. No wasted truck rolls.
"99.999% uptime means less than 5 minutes of downtime per year. When fiber breaks, every minute spent driving to the wrong span is a minute toward a SLA breach. We built Optical Path Engineering to close that gap — giving your field technicians the street address of a fiber fault in the time it takes to read this sentence. And when the job is done, every splice case, device, and circuit your Inside Plant team touches lives in a structured hub and data center database — so the next crew knows exactly what's patched where."
Designed by engineers who have driven those wrong spans. Built for OSP crews, Inside Plant teams, and the field technicians who can't afford to do it twice.
Two entire industries never talk to each other — and we built the thing that finally connects them.
EXFO, VIAVI, AFL, and others build test equipment that measures the fiber and reports a distance to the fault. That's the whole job — the device has no idea where that number lands on a map.
Esri, IQGeo, OSPInsight, VETRO, and others document where your plant is supposed to be. None of them read a raw .sor trace file, and none take a field correction back from a tech at a splice case.
Reads the number your OTDR already gives you, resolves it against whatever plant data you have, and writes clean, GPS-precise as-built data back into your system of record — in both directions.
This isn't a cheaper alternative to either category — every fault response and every splice case captured makes your underlying plant data more accurate. Built for daily use, not a specialty tool that sits idle between incidents.
Whether you're responding to a fiber cut at 2 AM or building out documentation for a new hub, Optical Path Engineering gives your team the data precision to move faster.
Turn OTDR fault distance into a GPS address. Export from your internal mapping system (GIS, OSS, or network documentation platform), snap the route to roads, attach a .sor file, and get a map pin at the break — with a reverse-geocoded street address ready to hand to a field crew. Three import modes: mapping system export, GPS coordinates, or fully manual draw.

Document facilities, racks, patch panels, preterm circuits, and cross-connects in a structured database that scales from a single cable hub all the way to a full data center. Know exactly what's patched where before you roll a truck. Auto-calc for power, HVAC, DC plant, generator, and rack power density.
Learn more →Independent fiber contractors and subcontractors carry OTDRs every day. They can measure a fault down to 6.234 km. But without a GIS system, without a mapping platform, without an NOC behind them — that number is just a number. There's been no affordable software built for the tech in the field who works alone.
The Single User tier closes that gap — full Fiber Damage Locator, one person, one login.
Contractors don't just find faults — they build splice cases, splitters, and taps every day, then have to hand the service provider clean as-built records for their GIS. That's usually a separate, manual chore: a hand sketch, a spreadsheet typed up after the fact, GPS coordinates estimated from memory.
Manual Draw now doubles as an as-built capture tool. When the job's done, export one package — ready to hand over, not built by hand afterward.
Export splice case GPS coordinates from your internal GIS or network mapping system. Upload the spreadsheet or CSV — no special format needed.
Each span checks whether a road plausibly runs along the fiber's path — not just whether one exists nearby — before snapping. Otherwise it stays straight-line between splice cases.
Drop in the OTDR trace. The fault distance is read automatically. Choose which end the trace was shot from.
Click Locate Fault. A red pin drops at the fault GPS coordinate with the nearest street address — ready for dispatch.

Don't have your plant documented yet? Before the software can help, the data has to exist. We handle that for you.
We built this because OTDR hardware and GIS/OSS platforms were never designed to talk to each other — not because either one did anything wrong. We're actively working toward direct integration partnerships with OTDR manufacturers and GIS/OSS platforms, so this bridge eventually needs no manual export or upload step at all. If you build OTDR hardware or a GIS/OSS platform, we want to talk.
