Wavelength meter 8612 series

The wavelength meters are an essential tool for measuring DWDM signals, calibrating fixed-wavelength and tunable transmitter lasers, featuring high resolution, accuracy and repetition rate. The broadband mode supports to high-rate modulated signals. The Keysight 86122C Multi-Wavelength Meter is now available with a faster update rate. The new option 86122C-110 accelerates the update rate from 2 per second to 3 per second. The wavelength measurement cycle time is reduced from 0.5 seconds to 0.3 seconds. For compatibility, the previous update rate of 86122C multi-wavelength meter is still available under option 86122C-100 For the measurement of light sources and signals in the wavelength range from 700 nm to 1700 nm, the 86120D Multi-Wavelength Meter offers a compelling set of features with ±1.5 ppm accuracy and a measurement cycle time of 0.6 seconds. Like for the 86122C, all wavelength accuracy specifications apply to single-scan measurements — there is no averaging required. This makes them ideal for fast, automated wavelength adjustment procedures.
