PolaritySolver DC by Anvilfield
Draw the exact Tx-to-Rx chain before you plug in MPO/MTP trunks
Pick Method A, B or C, cassettes, jumper, gender, endface and endpoints. The app draws the polarity chain fiber by fiber, catches the double-flip, checks mate gates, saves racks and exports records - offline, with no account.
Built for the data-center fiber tech
- Solve Method A/B/C polarity for base-8 and base-12 MPO/MTP arrays.
- Check pinned gender, APC/UPC endface mates, and the double-flip before you land trunks.
- Save rack configs and export a PDF or CSV record for the closeout packet.
Free and Pro
Solve, mate gates and one saved rack are free. Pro adds reverse diagnostics, array mode, export, pinned standards and unlimited saved racks for a one-time $9.99 through Google Play billing. Once purchased, Pro is cached on the device and stays active offline.
Scope
PolaritySolver DC is a planning aid. It tells you what the chain should be; the OLTS PASS and closeout acceptance are the gate. Verify against the actual part labels and the test set. MTP is a US Conec trademark. This app is manufacturer-neutral and does not reprint vendor pinout diagrams.
