  • Page 121 Definitions and Calculation Methods Bandwidth (nm) Bandwidth is the spectral width over which the attenuation of the device exceeds some stated loss value. The system can measure bandwidth at three different attenuation levels, called BW1, BW2, and BW3, relative to the minimum attenuation level, as illustrated in the following diagram.
  • Page 122 In this method, you specify the wavelength range to use for the evaluation. You will have to provide a span range centered around the ITU CWDM central wavelength. As shown in the diagrams, the wavelength range for BW1 and ITU bandpass is different and the resulting calculations will be different. IQS-12008...
  • Page 123 Definitions and Calculation Methods Central Wavelength (nm) The central wavelength is the wavelength at the midpoint between the lower and upper wavelengths at BW1 dB level from the peak. Note that the central wavelength is not necessarily the peak wavelength. 0 dB loss line 3 dB Increasing loss...
