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.

在以往的研究项目中，设计了一种用于光正交频分复用传输的发射机集成电路。该电路可支持实时数据传输，数据传输速率可达500gbit /s。本方案针对设计的发射机电路的特性，以及在发射机中使用该电路进行光数据传输实验。由于该电路是为实时传输而设计的，因此需要适当的印刷电路板设计来支持发送电路所需的输入数据速率，并对该电路的数字部分以及两个集成数模转换器进行表征。首先，数字信号处理器的功能以及集成电路上数模转换器的采样率和分辨率必须在印刷电路板上使用适当的测试程序进行验证。在第二阶段，传输实验将与INÜ的研究小组一起进行。最后合作演示数据速率高达半TB/s的实时光数据传输实验。
