OPTICAL WAVELENGTH METER
An Optical Wavelength Meter measures the peak wavelength(s) of an optical signal with extreme precision, often to picometer and sub picometer accuracy.
The use of proven Michelson interferometer technology coupled with an advanced FFT algorithm allows measurement of modulated and non-modulated signals from an optical transceiver. A flexible display can measure and display a single or multiple wavelengths (such as from a DWDM system) in a single operation.
Yokogawa's Optical Wavelength Meter offers an industry first extended life internal reference laser to maximize the usage time between intrusive maintenance tasks in today's demanding high speed optical R&D, as well as manufacturing applications.
