The transition to 400G is in full swing with volumes of 400G system ports and pluggables increasing significantly. However, even as 400G becomes more commonplace, the insatiable demand for bandwidth means the next technological advancement is already in the making. 800G is around the corner and, at 112G per channel, brings with it a myriad of unique test challenges.
The 112G HSIO ecosystem compels semiconductor and system vendors to rely on new techniques and technologies to validate their designs. Novel equalization methods carry the major responsibility of recovering lossy signals and must be characterized in realistic environments.
The MultiLane ML4067-112-24 112G channel board is an ideal tool for this purpose. Featuring a variety of carefully designed differential test traces, this passive test accessory adds precise ISI (inter-symbol interference) in order to calibrate or stress test DSPs, modules, gearboxes or other relevant systems in real-life environments.
