AUA-330U/A Optical Power Meter for ONT/OLT — 1310nm / 1490nm / 1550nm, UPC Port, ±0.5dB Precision

The AUA-330U/A optical power meter measures three fiber wavelengths at once — 1310nm, 1490nm and 1550nm — with a measurement control error within ±0.5dB. Its dual pass‑through ports allow testing without interrupting communication between OLT and ONT. LED-assisted connector handling enables quick on-site swapping to SC or FC UPC interfaces. The unit is powered by a single 9V alkaline battery and is protected by a soft silicone cover to reduce damage from drops and impacts.
