The Exfo IQS-3150 Series Variable Attenuators are versatile variable attenuators. It can be used as a regular attenuator or it can be equipped with an integrated power meter, which allows you to work not only in attenuation but also in power level requirements.

The IQS-3150 modules are high-performance attenuator modules, part of the IQS product line. The modules are configured for singlemode or multimode fibers and complies with optical return loss measurement (ORL) standards on transmission equipment. The IQS-3150 Variable Attenuator is available in four models: standard singlemode, standard multimode, self-adjusting singlemode, and self-adjusting multimode. The self-adjusting modules offer two operation modes: Attenuation and Power Output. The Attenuation mode allows you to work with a wide range of attenuation levels. The Output Power mode allows you to request a fixed output power value and the module automatically adjusts the attenuation according to that value.

The IQS-3150 Variable Attenuator supports local control (via the IQS Manager software) and remote control (through GPIB, RS-232, or Ethernet TCP/IP using SCPI commands or the provided LabVIEW drivers).

Product Family: IQS-3150, IQS-3150-C-EI
