Plan the network. Calculate the loss. Then prove it actually works.
FiberLink is a fiber-optic network design and diagnostic tool built for the people who actually build GPON, FTTH, and point-to-point networks — not a spreadsheet, not a desktop licence, just the phone you already carry to site.
NEW: TEST & TROUBLESHOOT
Log a real power-meter reading at any point in your network and get an instant verdict — pass, marginal, or fail — with the real reason behind it, so you know whether it's a bad splice upstream or simply outside your receiver's window. Set your own pass/fail thresholds, or use built-in GPON Class B+ / Class C+ presets. Tag every reading with GPS and open it straight in Google Maps. Export a full diagnosis report as a PDF.
DESIGN & CALCULATE
Model your network as a live graph — headend, splitters, drops — and watch the optical loss budget calculate in dBm as you add every splice, splitter, and span. Any split ratio from 1:4 to 1:128, plus percentage taps. See exactly what power reaches every endpoint before you ever touch a cable.
BUILT FOR THE FIELD
• Custom numeric keypad for fast, accurate readings — no fumbling with the on-screen keyboard
• Step-by-step loss-math breakdown under every coupler
• GPS-tagged readings, opened directly in Google Maps
• One-tap PDF export for client and compliance reports
• Works offline — no signal required on site
WHO IT'S FOR
FTTH installers, GPON technicians, network planners, and anyone who needs to answer one question with confidence: does this fiber link actually work?
Whether you're designing a new build or troubleshooting a complaint on an existing one, FiberLink turns "does this work?" into a number you can trust.
