ID Photonics ups IQ Multi-Format Transmitter bandwidth to 40 GHz for 64-GBaud applications

German test and measurement systems vendor ID Photonics has increased the RF bandwidth of its IQ Multi-Format Transmitter to more than 40 GHz. The bandwidth increase enables technicians to use the system to evaluate coherent transmission technology designs targeting 64 GBaud.

The IQ Multi-Format Transmitter works with arbitrary waveform generators (AWGs) such as Keysight Technologies' M8196A to enable generation of high-speed signals for laboratory applications. The unit converts four RF waveforms (I and Q in X and Y polarization, respectively) coming from the AWG into a dual-polarization IQ modulated optical signal.

The system features pattern-independent automatic bias control (ABC) for optimal performance regardless of modulation format enabled by the company's zero noise feature. Researchers can change modulation formats and symbol rates seamlessly while maintaining the modulators bias stability, the company asserts. This ability makes the system useful for automated impairment and stress testing in a manner that reduces product development cycles, ID Photonics adds.

"The significant bandwidth enhancement of our multi-format transmitter allows researchers to unleash the full potential of the latest arbitrary waveform generator instruments available. High-fidelity constellations at up to 64 GBaud can only be achieved if proper matching of both electrical signal source and E/O converter is achieved. By providing calibration files that can be seamlessly integrated into Keysight's latest AWG product line, we have the unique capability to generate these high-fidelity signals," said David Stahl, general manager of ID Photonics.

The IQ Multi-Format Transmitter is commercially available immediately in multiple configurations, including full-dual polarization, emulated dual polarization, and single polarization.
