NEMA Guide vs MapYourOTDR

Use the NEMA Guide app to quickly identify and cross-reference NEMA plug and receptacle configurations—a must-have tool for electricians and electrical professionals on the job. Whether you're trying to identify an unknown plug or need to confirm the right receptacle for a specific application, this app streamlines the process. Simply search by NEMA number or filter by voltage, amperage, phase, poles, wires, and grounding type to view all matching results. With illustrations and detailed specs for each configuration, to save you time and avoid guesswork on-site. Features: - Search by NEMA configuration number. - Filter by voltage, amperage, phase, poles, wires, and grounding. - Instantly view matching plug and receptacle configurations. - Over 170 high-quality configuration illustrations. - Tap to view detailed specs for each configuration. - Cross-reference plugs and receptacles with ease. - Data is stored locally for quick use in the field or on the job-site.

MapYourOTDR turns your iPhone or iPad into a full OTDR trace analyzer — read, interpret, and report on optical-fiber test data without the instrument's desktop software, and entirely offline. Open a Telcordia SR-4731 (.sor) file from any OTDR and get an interactive trace you can pinch-zoom, pan, and measure. Drop two markers to read the distance, loss, and attenuation across any span — the way you would on the instrument itself. WHAT IT DOES - Decode and plot .sor traces with full acquisition parameters - Automatic event classification — connectors, splices, gainers, ghosts, fiber end - A/B two-marker measurement: distance, 2-point loss, and dB/km - Link health score with a clear pass/fail verdict - ORL, section attenuation, uniformity, and a full loss-budget breakdown - Baseline comparison — overlay a commissioning trace and see exactly what changed - Bidirectional true splice loss — pair both directions and average out the backscatter bias (ITU-T G.650.3 method), with gainers resolved - Dual-wavelength macrobend detection — compare 1310 vs 1550 nm and flag bends that lose more at the longer wavelength - On-device PDF test reports, branded with your company and name - CSV export of the event table LEARN 23 illustrated, vendor-neutral topics covering dead zones, dynamic range, reflectance, ghosts, gainers, bidirectional testing, PON and splitter testing, multimode limits, OTDR variants, calibration, fiber types, and a field troubleshooting workflow. TOOLS Field calculators for distance, dead zone, reach from dynamic range, loss budget, optical-vs-route length, splitter loss, and averaging gain. SIMULATE Generate synthetic traces with seeded faults — connectors, splices, gainers, macrobends, ghost echoes — to practise reading them. PRIVACY No account, no tracking, no ads. Every trace is parsed, analyzed, and turned into a report on your device. Nothing is uploaded. Free to use: trace viewer, basic analysis, demo traces, the core simulator, and 7 LEARN topics. A one-time Pro unlock adds the full analysis engine, all 23 topics, every simulator fault, configurable thresholds, and PDF/CSV export. Built for fiber-optic field technicians and network engineers. Grounded in public standards — Telcordia SR-4731, ITU-T G.650.x / G.652 / G.657, IEC 61746, TIA-568.
