Optical Toolkit vs FiberView Pro

The Optical Toolkit is a professional reference app for optical networking engineers — the calculators, quick conversions, reference data, and OTDR trace handling you reach for every day, in one place that works fully offline. WHY THIS APP EXISTS It came from personal need. As a working optical engineer I kept needing a quick OSNR check, a unit conversion, a standards value, or a fast look at a .sor trace — and kept reaching for scattered spreadsheets, PDFs, and laptop tools. So I built the toolkit I wanted in my own pocket, and I am sharing it free so every engineer, student, and enthusiast who works with fiber can take advantage of it. CALCULATORS — 47 TOOLS Link design: OSNR span design with FEC presets, EOL budget, nonlinear phase, Raman hybrid noise figure, GOSNR combining, rise-time budget, SBS/SRS thresholds, fiber mode and cutoff, extinction-ratio penalty, and Shannon capacity with modulation targets. DWDM: coherent rate and OSNR planning, guard-band planning with vendor rules, channel capacity by band, and ITU grid tools. Converters: dBm/mW, OSNR/SNR, wavelength/frequency, and more. Every input carries units, ranges, and engineering presets; results include pass/fail verdicts and margins. OTDR TRACES ON YOUR PHONE Open .sor trace files directly. The reader decodes fixed parameters, key events, and data points, draws the trace with color-coded event markers, and produces an analysis report: span length, total loss, ORL, event classification against thresholds, and recommendations. FULL REFERENCE LIBRARY 59 reference tables — fiber standards (G.652 through G.657) side by side, coherent scaling laws, guard-band thumb rules, a channel quick database, transceiver formats — plus a 394-term glossary, 427 alarm definitions with troubleshooting, 550 specification parameters, and a master search across everything. BUILT FOR THE FIELD Everything works offline — airplane mode included. No account, no tracking, no analytics. SOR files are parsed on the device and never uploaded. Light and dark themes, adjustable fonts and text size, and favorites to pin the tools you use daily. Made by MapYourTech for optical, DWDM, and DCI engineers, students, and NOC teams.

FiberView Pro — Field Tools for Fiber Technicians FiberView Pro is the reference and documentation app built for fiber optic professionals. Four powerful tools in one fast, offline-ready app — color identification, field notes, audit tables, and drawing markups. No subscription. No account required. — FIBER COLOR IDENTIFICATION Instantly look up any fiber by tube and strand number across all major color coding standards. The visual ribbon chart gives you a color-accurate view of your entire cable layout at a glance. Your recent lookups are saved automatically so you can jump straight back to your last cable without starting over. Need something non-standard? Build custom cable configurations and save them for reuse across any job. — SMART NOTEPAD Take rich, formatted notes straight from the field. Bold, italic, underline, bullet lists — your documentation looks professional from the moment you write it. Organize notes into folders and smart folders that update automatically based on content. Start quickly with built-in templates for splice logs, strand notes, and job summaries. When the job is done, export any note as a clean PDF or print it directly from the app — ready for client handoffs and job closeout packages. — AUDIT TABLES Build structured inspection and audit tables without opening a spreadsheet. Create custom columns, enter test readings, and keep every table organized by job. When you're ready, export a polished, print-ready PDF to attach to work orders or send directly to clients. Smart folders surface your most recent audits automatically so your active work is always front and center. — REDLINE DRAWINGS Import any PDF — as-builts, floor plans, fiber diagrams — and mark them up right in the app. Annotate with arrows, shapes, freehand ink, and text labels. Pinch to zoom and pan through multi-page documents with precision. When your markup is complete, export a finished redlined PDF ready for engineering review or client approval. No laptop. No desktop software. No extra steps. — ICLOUD SYNC Your notes, tables, and redlines sync automatically across all your Apple devices via iCloud. Start a note on iPhone in the field and review it on your iPad back at the office — no setup required. — Works fully offline. Your data stays on your device and in your iCloud. Built by technicians, for technicians.
