Modulator output (IMAGE) Kyushu University Caption Waveforms of data transmitted at 200 Gbit/s using a hybrid-polymer modulator developed by researchers in Japan and capable of operating at temperatures up to 110 °C. The signals can take one of four different levels that correspond to two bits each, resulting in three holes in the overlapping signals.
