Technologies and Products

ECOC 2023: Quantifi Photonics releases VISIQ™ software for advanced coherent optical signal analysis.

Quantifi Photonics has released VISIQ™, what it says is the first coherent optical signal analysis software that is compatible with high-speed oscilloscopes from manufacturers including Keysight Technologies, Tektronix and Teledyne Lecroy. VISIQ is designed to make coherent signal analysis and DSP optimisation as simple as possible. It features an intuitive user-interface that reduces the learning curve for new users, while still providing the ability for advanced users to fully customise the signal processing algorithms.

From the VISIQ interface, users can control system hardware, configure digital signal processing workflows and view detailed signal properties with comprehensive visualisation options. Advanced features such as coherent receiver auto-calibration, auto baud rate detection, adaptive equaliser and nonlinear correction algorithms significantly reduce the set-up time and optimise system performance.

Iannick Monfils, CTO of Quantifi Photonics says, “VISIQ is a significant step forward for the optical communications industry.  It is designed to work with all popular high-speed real-time oscilloscopes, enabling coherent signal analysis for customers with existing hardware systems but don’t have suitable analysis software, or want an improved software user experience.” He added, “Existing analysis software can be time-consuming to learn and isn’t particularly easy to use, even for experienced engineers. We have spent considerable time developing this software with users and expect it to significantly speed up complex optical signal analysis; helping the industry develop and commercialise new coherent technologies faster than they could before.”

Key features include:

• Oscilloscope agnostic: VISIQ works with high-speed oscilloscopes from manufacturers including Keysight Technologies, Tektronix and Teledyne Lecroy.
• User-friendly GUI: Features a modern user-friendly interface designed for novices and experts, streamlining the analysis process and reducing the learning curve.
• Intuitive DSP pipeline: VISIQ features drag-and-drop reconfigurable functional nodes for intuitive configuration of analysis workflow. This approach allows users to try different DSP configurations with immediate feedback, so the users can quickly learn how to optimise their coherent DSP and detect and address any signal anomalies or performance fluctuations.
• Automatic hardware discovery and integrated hardware control: VISIQ automatically discovers compatible coherent receiver and oscilloscope hardware on the USB or Ethernet network. Users can also control the oscilloscope, coherent receiver and the internal laser within the VISIQ software interface.
• Broad technology support: Supports O-band coherent modulation analysis with Quantifi Photonics’ O-band IQRX, in addition to C- and L-band, as well as development of next-generation 800ZR and 1600 ZR coherent transceivers.
• Improved efficiency: Coherent receiver auto calibration, auto baud rate detection, adaptive equaliser and nonlinear correction algorithms significantly reduce the set-up time and optimise system performance.
• Powerful adaptive equalisers: VISIQ’s advanced equaliser algorithm can be set to train over multiple iterations to test the boundaries of DSP signal optimisation and boost test efficiency.
• Remote control and automation: VISIQ supports SCPI and gRPC controls for test automation.

Quantifi Photonics will be hosting a demonstration of VISIQ at ECOC 2023, 2-4 October, booth 353.
