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.

这项建议是基于斯图加特大学电气和光通信工程研究所(INT)和电信研究所(INUE)的合作。在前期课题“高码率光正交频分复用系统的电气关键器件”中，我们成功地设计了一款单偏振速率达到165Gbit/S的实时光发射专用集成电路。为了测试ASIC的功能，我们计划设计一个相应的接收器来分析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，还计划进行光传输实验，首次演示了使用实时OFDM机在单极化情况下的比特率显著高于100Gbit/S。
