Power Meter -850/980/1310/1490/1550/1625
The OPM 4 optical power meter may be used to measure optical power in Premises, Telco, or Broadband fiber optic networks. When used with an LED or Laser light source, the OPM 4 also measures insertion loss of multimode or single-mode cables. The OPM 4 offers Wave ID, automatic wavelength identification and switching, when used with the OLS 1 Dual or OLS 2 Dual or OLS 4 with Wave ID feature. Multiple test Tone detection is provided for fiber identification. The OPM 4 stores optical references for each calibrated wavelength. An easy to read Dual Wavelength LCD display with Backlight shows measured power [dBm or μW] or insertion loss [dB], calibrated wavelengths, tone signal [Hz], wavelength ID, and the battery charge status. In addition to being powered by two AA alkaline, the OPM 4 can be powered by optional AC adapter and/or rechargeable NiMH battery pack. The OPM 4 optical input port accepts Noyes thread-on style adapter caps. Adapter caps are required for operation and must be ordered separately. The OPM 4 is fully N.I.S.T. traceable.
