Multi-Wavelength Meter

Multi-Wavelength Meter

The 438 Series measures the wavelength, power, and OSNR of as many as 1000 discrete optical signals. With key features such as high accuracy, fast measurement rate, straightforward operation, and rugged design, the model 438 provides the most precise, reliable, and efficient WDM wavelength testing available. Wavelength is measured to an accuracy as high as 0.3 pm, power is measured to an accuracy of 0.5 dB, and OSNR is automatically calculated to greater than 40 dB. A measurement rate of 10 Hz enables a reduction in wavelength testing times for greater manufacturing productivity.
