The NOYES OPM4-3D is a hand-held optical power meter designed for measuring optical power in premise, Telco, or broadband networks and for performing insertion loss measurements on multimode or single-mode fiber optic links. When used with NOYES OLS series light sources, the OPM4 offers automatic wavelength identification and switching-Wave ID feature that automatically detects and sets the wavelength(s), preventing setup and measurement errors. It significantly increases efficiency and reduces technician errors—and saves testing time—by eliminating the need to test each wavelength individually. The OPM4-3D stores optical references for each calibrated wavelength and offers multiple test tone detection for fiber identification. The OPM4 optical input port accepts a variety of NOYES thread-on style adapter caps (ordered separately) to meet a wide range of testing requirements. The OPM4-3D offers a five-minute auto-off feature and long battery life from common AA alkaline batteries. Specifications. Calibrated Wavelengths: 850, 1300, 1310, 1490, 1550, 1625 nm. Detector Type: InGaAs. Measurement Range: +10 to -75 dBm. Tone Detect Range: +10 to -50 dBm (+10 to -45 for 850 nm ). Wavelength ID Range: +6 to -50 dBm (+6 to -45 dBm for 850 nm). Accuracy (measured at 25ºC and -10 dBm): ±0.25 dB. Resolution: 0.01 dB. Measurement Units: dB, dBm, µW.
