Keysight Technologies recently announced the new N7005A optical-to-electrical converter designed for use with Keysight's Infiniium UXR-series of high performance real-time oscilloscopes. This solution provides real-time analysis and debug capabilities on up to 4 channels simultaneously, offering designers new testing methodologies.
As demand for IoT-based applications, HD streaming, cloud services and 5G continues to increase, the need for higher data throughput communication and more efficient test solutions in the optical domain steadily grows as well. 400G with PAM4 signaling is more complicated than 100G with non-return-to-zero (NRZ) modulation and significantly increases the required time for design validation, debug and troubleshooting cycles (more info, photo: Reproduced with Permission, Courtesy of Keysight Technologies, Inc.).
