With the popularization of data center and other bandwidth hungry inter-connect applications, the desired capacity of short reach optical network has exponentially increased. In order to realize high-speed transmission, a few modulation formats or schemes, such as PAM4 and DMT are proposed and experimentally demonstrated. However, these modulation formats need expensive DAC and ADC as well as DSP procession. OOK modulation has simple architecture and high receiver sensitivity. Duo-binary signal is a special OOK signal. Here we experimentally demonstrate a record bit rate of 160-Gb/s OOK electrical signal generation, and realize a duobinary optical signal at a bit rate of 160Gb/s transmission and detection.
