Full-featured, handheld optical power meter

NOYES OPM4 is designed for measuring optical power in all network types and performing insertion loss measurements on multimode or single-mode fibre optic links. The OPM4 is fully N.I.S.T. traceable. 

Automatic Wavelength Identification Significantly Increases Efficiency

The standard Wave ID feature automatically detects and sets the receive wavelength(s), preventing setup and measurement errors (when used with NOYES OLS series light sources). It significantly increases efficiency and reduces technician errors—and saves testing time—by eliminating the need to test each wavelength individually.

Optical References Storage

The OPM4 stores optical references for each calibrated wavelength and offers multiple test tone detection for fibre identification.
