The Agilent 86120B Multi-Wavelength Meter is a Michelson interferometer-based instrument that measures wavelength and optical power of laser light in the 700 to 1650 nm wavelength range. Simultaneous measurements of multiple laser lines are performed allowing measurements of WDM (wavelength division multiplexed) signals and multiple lines of FabryPerot lasers. Each laser line is assumed to have a linewidth of less than 10 GHz.
