ML4015E Optical and Electrical Sampling Oscilloscope Ideal for 53.125 GBaud PAM4 and NRZ transceiver testing | Supports 802.3 TDECQ measurements via SSPRQ patterns | Open Eye MSA support | 100G per wavelength and channel characterization Currently the Data Center Interconnect market is rapidly transitioning to 100G per channel for both optical, as well electrical interfaces, with the introduction of 800G Ethernet. Cost-effective characterization tools are required to enable this technology transition and to accelerate the deployment of 800G Data Center Interconnects, such as optical transceivers. The characterization of Ethernet transceivers introduces a myriad of test and measurement challenges. For instance, precise validation of 53.125 GBaud PAM4 optical transmitters requires prohibitively expensive instrumentation setups for production applications. MultiLane introduces the ML4015E Optical and Electrical Sampling Oscilloscopes as a well-correlated alternative to incumbent solutions at a high-value price point.
