Coherent Optical Receiver

The IQRX is a “gold standard” coherent receiver for the measurement of coherent modulation formats such as QPSK, 64QAM and OFDM.
Its high-bandwidth, low-noise architecture makes it ideal for high-quality, low-distortion coherent signal measurement.
With two built-in lasers and convenient touchscreen LCD front panel control, the IQRX delivers quick and reliable measurements.

Automatic Bias Controller

MATRIQ-IQABC - Quantifi Photonics Inc.

Optimizing DC bias points of an IQ modulator is no trivial task. There are six different Mach-Zehnder structures inside one dual polarization IQ modulator, all simultaneously influencing the properties of a single optical signal. Trying to optimize bias points using just the intensity measurement of the optical signal is time consuming, inaccurate and it requires a lot of knowledge and experience.

Automated Coherent Receiver Tester

CoRx Tester. - Quantifi Photonics Inc.

Quantifi Photonics’ CoRx Tester provides automated measurement of key coherent receiver performance parameters. The CoRx Tester is comprised of a pre-configured PXI chassis, a two-channel tunable laser, a polarization controller, and a two-channel Variable Optical Attenuator (VOA) with built-in power meter. Just connect the two optical outputs to your Integrated Coherent Receiver (ICR), connect your ICR to the oscilloscope and let the CoRx Tester software do all the rest.
