    Introducing the IQ-3100/IQ-3300 IQ-3100 Variable Attenuator The IQ-3100 Variable Attenuator module is a high performance attenuator that is part of the IQ-200 Optical Test System product line. High quality components and meticulous calibration procedures ensure that the IQ-3100 Variable Attenuator achieves repeatable and precise attenuation settings (up to 100 dB).
  • Page 9 IQ-200 Optical Test System. Definition of Attenuation The attenuation displayed by the IQ-3100 is the actual loss between the input and output ports including the attenuator’s internal connectors. The attenuation value is a negative number. The B value in the X+B mode is a correction factor applied to a specific wavelength.

    Due to the internal optics of the IQ-3100 (and the majority of attenuators), most of the cladding modes are filtered out. This means, with the attenuator connected, the power meter will display a loss greater than the attenuation setting of the attenuator (cladding modes have been partially stripped).
