    The new Q8326 Optical Wavelength Meter enables designers, manufacturers and users of dense wavelength division multiplexing (DWDM) components to quickly and accurately test the compliance of next-generation transmission laser diodes. Tolerances of these diodes have narrowed due to the increased bandwidth demands of the Internet. The Q8326 has a high wavelength accuracy of ±2 ppm and makes measurements with a resolution of up to 0.1 picometers. A sampling rate of 5 measurements/s enables a quick evaluation of laser diodes, which saves time and money during the manufacturing test and incoming inspection stages, the company says.
    Another feature--the deviation display function--captures with high resolution and accuracy any minute wavelength fluctuations caused by temperature variations. In addition, the Q8326 instrument can be used as a wavelength standard for the calibration of optical spectrum analyzers and tunable lasers.
    The Q8326 Optical Wavelength Meter is priced at $21,950 and is available now, with a delivery time of six weeks ARO.
