Elektronische Schlüsselbausteine für optische OFDM-Systeme hoher Bitrate

在前期的研究项目中，我们设计了一个用于光正交频分复用传输的发射机集成电路。该电路可以支持实时数据传输的数据速率高达500 Gbit/s的使用偏振复用的光纤。该建议是针对所设计的发射机电路的特性，以及在发射机中使用该电路的光数据传输实验。由于电路设计用于实时传输，因此需要适当的印刷电路板设计来支持发送器电路所需的输入数据速率，并表征数字部分以及电路的两个集成数模转换器。首先，必须在印刷电路板上使用适当的测试程序来验证数字信号处理器的功能以及集成电路上的数模转换器的采样速率和分辨率。在第二阶段，将与研究所的研究小组一起进行传输实验。最后，将合作演示数据速率高达半TB/s的实时光学数据传输实验。

In the previous research project a transmitter integrated circuit has been designed for optical orthotogonal frequency division multiplex transmission. The circuit can support real-time data transmissions for data rates be operated up to 500 Gbit/s using polarization multiplex over the fiber. This proposal is targeting for the characterization of the designed transmitter circuit as well as for optical data transmission experiments using this circuit in the transmitter. As the circuit is designed for real-time transmission appropriate printed circuit board designs are required to support the required input data rate to the transmitter circuit and to characterize the digital part as well as the two integrated digital-to-analog-converters of the circuit. At first the functionality of the digital signal processor as well as the sampling rate and the resolution of the digital-to-analog-converters on the integrated circuits have to be verified using adequate test procedures on the printed circuit board. In a second phase transmission experiments will be performed together with the research group of the INÜ. Finally real-time optical-data transmission experiments with data rates up to half a TB/s will be demonstrated in cooperation.
