otsora

otsora is a private, on-device otdr trace viewer for fiber-optic technicians.

open a .sor file from anywhere — files, airdrop, email — and get an instant analysis:
· fiber length, total loss, optical return loss
· per-event splice loss, reflectance, slope
· vendor-quirk handling for exfo, viavi, anritsu, yokogawa, jdsu

export any single-core analysis as a pdf link report.

cable pro (one-time purchase)
· analyze a multi-core cable in one pass — 1 to 288 cores
· ranked repair locations across cores (splice clusters within 200 m)
· per-core verdict + end-event classification (cut, crushed, mated pc, off-route…)
· attach a kml/kmz route and see exactly where on the map to send a crew
· watermark-free cable + per-core pdf reports

try cable pro free for 7 days. no subscription and no automatic charge. after the trial, unlock pro permanently with one payment of US$15 (local prices vary). the single-core viewer stays free. restore your purchase from the account tab.

private by design — traces never leave the device. no account, no upload, no telemetry.
