The NOYES OPM4 is a hand-held optical power meter series is 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 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 offers a five-minute auto-off feature and long battery life from common AA alkaline batteries. Features. Multimode or single-mode applications. Wave ID (auto identification and switching).
