OTDRCheck screens your contractor's OTDR PDF test reports against your acceptance thresholds — surfacing the fibers that need a closer look, so your team isn't manually combing through thousands of files to find them.
Request a Free Sample Analysis See How It WorksWhen a contractor completes a fiber build — whether it's BEAD-funded, a USDA ReConnect project, a state grant, or a private deployment — they hand you a package of OTDR test reports, sometimes thousands of them. Those files are the documented record of how every fiber span tested at the time of installation.
OTDRCheck was built to change that. We give the people responsible for verifying fiber construction the same ability to screen test data that the people generating it have had for years — so your engineering team knows exactly where to focus their review.
OTDRCheck reads your contractor's OTDR PDF test reports, compares every extracted measurement against the acceptance thresholds you provide, and returns a structured screening report showing:
A complete list of fibers where extracted measurements fall within your stated criteria — organized for efficient engineering review.
Exact measurement, location, and threshold deviation for every fiber that didn't meet criteria — so your engineers know precisely where to look.
Readable, organized output your engineering team can work from — sorted by fiber, measurement type, and deviation for efficient acceptance review.
Three steps to a systematic, independent screening of your OTDR deliverable package. No OTDR software to install — your engineering team reviews the results and makes acceptance decisions.
Send us your OTDR PDF test reports and your project's acceptance thresholds. We support reports from Viavi, EXFO, JDSU, Noyes, and more.
We process your files against the thresholds you provide and generate a complete screening report, typically within 48 hours of payment confirmation.
A structured report showing which spans met your thresholds, which were flagged, and the exact measurements — so your engineering team can focus their review where it actually matters.
OTDRCheck is designed for project owners, engineers, and administrators — not contractors. If you're responsible for reviewing that a build meets spec before you release payment, this is a tool for your team.
Administering BEAD grants and need a systematic way to screen acceptance documentation before releasing funds.
Expanding networks with federal grant money and contractor-managed construction.
Deploying fiber to members and need independent screening of contractor test deliverables.
Managing federal broadband buildouts and need systematic screening of acceptance test data.
Responsible for reviewing construction quality before final payment is released.
Ensuring federally funded projects are reviewed for performance requirements and properly documented.
We price based on project scope — no subscriptions, no surprises. Request a quote and we'll confirm the right tier for your deliverable package. All tiers include a structured screening report for your engineering team's review.
Tell us about your project and we'll follow up within one business day. Your files are kept strictly confidential.
OTDRCheck is built by outside plant engineering veterans with over 35 years of hands-on experience designing, managing, and overseeing fiber builds across rural America. We've been on both sides of the table — managing construction crews and reviewing contractor deliverables — and we built OTDRCheck because no systematic screening tool existed for the people responsible for verifying what they were paying for.
The defects are usually right there in the data. The problem has always been finding them.
