Optical Power Meter Telecommunication Wavelength
NIST (the US National Institute of Standards and Technology) provides power meter calibration at these three wavelengths for fiber optics. Multimode fiber is designed to operate at 850 and 1300 nm, while singlemode fiber is optimized for 1310 and 1550 nm. When talking about optical measurements, wavelength basically means how far a wave pattern repeats itself, usually measured in nanometers (nm). Understanding this becomes really important when measuring power levels since different wavelengths get absorbed differently by materials, which affects. Plastic optical fiber (POF) is made from materials that have lower absorption at shorter wavelengths, so red light at 650 nm is commonly used with POF, but at 850 nm attenuation is still acceptable so short wavelength glass fiber transmitters may be used. Other general purpose light power measuring devices are usually called radiometers, photometers, laser power. Since optical fiber power meters (OFPMs) are a very common type of optical test equipment, NIST has developed and implemented measurement services to help characterize these instruments.
