Product Description

Power Meter -850/980/1310/1490/1550/1625

The OPM5 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 5 also measures insertion loss of multimode or single-mode cables.

The OPM5 offers Wave ID, automatic wavelength identification and switching, when used with the OLS1-Dual, OLS2-Dual, or OLS4 with Wave ID feature. Multiple test Tone detection is provided for fiber identification. The OPM5 stores optical references for each calibrated wavelength. An easy to read Dual Wavelength LCD display with Backlight shows measured power [dBm or ?W] or insertion loss [dB], calibrated wavelengths, tone signal [Hz], wavelength ID, and the battery charge status. Up to 500 records per wavelength of power or insertion loss measurements may be stored in internal non-volatile memory.

Using the supplied Windows® compatible software and USB connection, test records may be transferred to a PC for storage, display, printing, and analysis. In addition to being powered by two AA alkaline, the OPM5 can be powered by optional AC adapter and/or rechargeable NiMH battery pack. The OPM5 optical input port accepts Noyes thread-on style adapter caps. Adapter caps are required for operation and must be ordered separately.

The OPM5 is fully N.I.S.T. traceable.
