The fibreSales FM-OPM Mini Optical Fibre Power Meter is a compact, portable test instrument designed for optical power measurement during the installation, operation, testing and maintenance of fibre optic networks.
The FM-OPM combines a broad 800–1650 nm wavelength range with 0.01 dB resolution, six calibrated wavelengths, an InGaAs detector and a large backlit LCD display.
Its lightweight handheld design makes it practical for technicians working across telecommunications, CATV, fibre laboratories, optical fibre sensor systems and general fibre network maintenance.
