The EXFO IQS-3150 is a precision variable optical attenuator designed for use within EXFO’s IQS modular testing platform. It allows controlled signal attenuation for singlemode fiber networks, making it essential for stress testing and power-level simulations during optical component and system qualification.
Users can program attenuation in fine steps or set it to a specific value to simulate fixed loss, enabling accurate BER and link margin testing. The IQS-3150 supports wavelength ranges typically from 1260 to 1650 nm and is equipped with low insertion loss and high return loss performance to minimize test influence.
The module integrates seamlessly into automated testing systems and can be controlled locally or via EXFO software. It is used extensively in labs, manufacturing, and network development where variable optical signal levels must be accurately replicated.
