Electrical key components for high-bitrate optical OFDM systems

该提案基于斯图加特大学电气和光学通信工程研究所（INT）和电信研究所（INUE）的合作。在之前的项目“高比特率光OFDM系统的电气关键部件”中，我们成功地设计了一个在一个偏振方向上达到165 Gbit/s的实时OFDM发射机ASIC。目前，该ASIC已由INT准备生产，为了测试ASIC的功能，我们计划设计一个相应的接收器，以分析ASIC产生的信号。这是必要的，因为OFDM信号类似于噪声，不能仅使用示波器进行分析。此外，还计划进行一项光传输实验，首次使用实时OFDM发射机在一个偏振方向上实现远高于100 Gbit/s的比特率。

This proposal is based on a collaboration of the Institute of Electrical and Optical Communications Engineering (INT) and the Institute of Telecommunications (INUE) of the University of Stuttgart. During the previous project "Electrical key components for high-bitrate optical OFDM systems" we successfully designed a realtime OFDM transmitter ASIC that reaches 165 Gbit/s on one polarization. Currently, the ASIC is prepared for production by the INT.For testing the functionalitiy of the ASIC we plan to design an according receiver in order to analyze the signal generated by the ASIC. This is necessary because OFDM signals resemble noise and cannot be analysed using an oscilloscope only. Furthermore, an optical transmission experiment is planned demonstrating, for the first time, bitrates considerably higher than 100 Gbit/s on one polarization using a realtime OFDM transmitter.
