About

Field Capture

Features
Read full description

Field Capture is the official field documentation app for Tempo T5600 OPM and T5800 SLS test instruments. Built for fiber optic technicians doing multi-unit work — FTTH deployments, OSP new construction, data center pre-commissioning, and enterprise network builds — it replaces paper logs and manual transcription entirely. CONNECT YOUR METER. CAPTURE IN ONE TAP. Connect your Tempo T5600 OPM via Bluetooth. The app mirrors the reading directly from the instrument — no manual entry, no rounding errors, no clipboard. Tap Capture and the reading is saved with a timestamp, GPS coordinates, address, and pass/fail status automatically. ORGANIZED BY JOB AND UNIT Create a job for each site or project. Assign unit numbers as you test. Every reading lives in its own job record, filterable by pass/fail status, or date. Progress tracks automatically as units are completed. PASS/FAIL THRESHOLD CHECKING Set a dBm threshold at the job level. The app evaluates every reading against it instantly — no mental math, no rechecking notes at the end of the day. EXPORT AND SHARE — CSV OR PDF When the job is done, export a complete record directly from your phone. Both formats contain every reading with full detail: unit number, power level (dBm), insertion loss (dB) (if applicable), pass/fail status, technician ID, GPS coordinates, address, and timestamp. Choose CSV for data analysis in Excel or Google Sheets, or PDF for a formatted report you can hand to a customer or your boss the same day the work is done. Share via email, AirDrop, or any file app on your device. WHO IT’S FOR Designed for FTTH contractors, OSP field technicians, data center commissioning teams, and systems integrators who need traceable, exportable fiber test records — not just numbers on a meter screen. REQUIREMENTS Requires a Tempo T5600 (OPM) or T5800 (SLS) with Bluetooth connectivity. This app captures and documents readings from the instrument — it does not generate optical measurements independently. This is a diagnostic documentation tool, not a fiber certification instrument.

Verdict

The call

Html Preview's advantage is update cadence (every 6 days vs every 3 weeks) and chart position (#149 vs unranked). On ads, in-app purchases and device support there is nothing between them.
