Ljósmælir OPM4 series
OPM4 Optical Power Meter
The Noyes OPM4 from AFL Telecommunications is a handheld optical power meter
designed for measuring optical power in Premises, Telco, or Broadband networks and for
performing insertion loss measurements on multimode or single-mode fiber optic links.
The OPM4 features automatic wavelength identification and switching (Wave ID)
when used with Noyes OLS series light sources, multiple test Tone detection for fiber
identification, and stores optical references for each calibrated wavelength. A large dualwavelength LCD display with backlight shows measured power [dBm or µW] or insertion
loss [dB], calibrated wavelengths [nm], tone signal [Hz], wavelength ID, and estimated
remaining battery life.
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 fiveminute auto-off feature and long battery life from common AA alkaline batteries.
The OPM4 is fully N.I.S.T. traceable.
