No signup, no email gate. The same first-pass checks our engineers run before a design review — free for the fiber and utility community. Results are engineering estimates; the stamped work is what we do for a living.
Check a GPON or XGS-PON link against ITU-T class budgets: splitter ratio, fiber length, connectors and splices, design margin — with a pass/fail verdict, receiver-overload check, and maximum reach. Shareable result links for design reviews.

Open the calculator →These tools produce screening-level engineering estimates and are not a substitute for a stamped analysis or a construction-ready design. When a project needs the real thing, that's our day job: pole loading analysis ($45–$75 per pole), FTTH design, and fiber network design from an in-house team of 600+ engineers. Active in 22 states. Available across all 50 U.S. states. Questions or a tool you'd like to see next? info@draftech.com
