1500 Series Power Meter and Light Source

The 1500 Series Power Meters and Light Sources are indispensable tools for fiber installation and maintenance. The Power Meter measures optical power and when paired with the LS-1500 Series Light Sources it will perform automatic loss measurements with wavelength recognition for up to three laser wavelengths. Pressing the store loss button records all three measurements for later downloading and analysis via its USB port. It stores up to 2,000 triple wavelength loss measurements.

The PM-1500 Power Meter greatly simplifies and expedites measurements of fiber optic links. It incorporates a highly sensitive and stable InGaAs detector with six calibrated wavelengths that afford the user a measurement range of +5 to -75 dBm. A high Powered version is available for CATV applications. All power meters and lights sources are equipped with universal adapters and are shipped with FC, ST and SC fittings. They are powered by a rechargeable Lithium Polymer battery and in a pinch can be powered by a standard 9V alkaline battery. The universal power adapter/charger is supplied with four interchangeable plugs.
