T5610	InGaAs OPM	$449.00
T5620	InGaAs (High Power) OPM	$449.00

Documenting hundreds of FTTH drops by hand means hundreds of handwritten readings to reconcile against unit numbers the next morning, never quite sure a reading passed or a photo was sharp.

The T5600 Series OPM (T5610 and T5620) and the free Field Capture app end that. Every reading logs itself over Bluetooth, stamped with GPS, organized by job and unit, and flagged pass or fail on the spot. The technician walks off the job with a clean CSV, no transcription, no photos to sort.

Precise InGaAs detector with ±0.09 dB calibration accuracy across thirteen wavelengths.

Field-Ready 300-hour battery from 2× AA cells, 500-reading memory, USB-C backup power.

APP-Connected Bluetooth capture, GPS logging, and one-tap CSV export through the Field Capture app.

Download the Field Capture App:

Pairs with the Field Capture app, Bluetooth capture, no manual entry

Documents splice points, cabinets, mux channels, or FTTH unit-by-unit

GPS, timestamp & tech ID auto-logged on every reading

One-tap CSV export, organized by job and unit

Pass/fail threshold check — green/red feedback at capture

InGaAs detector: +6 to −60 dBm (T5610) / +26 to −45 dBm (T5620)

Calibrated to 10 wavelengths, 850–1650 nm, covers SWDM, XGS-PON & 1625/1650 nm

Tone detection 200–2500 Hz identifies active fibers

300-hour battery from 2× AA — USB-C for continuous power

500-reading internal memory

3-year warranty
