| Abstract(in English) | We demonstrate the first real-time coherent optical transmission of a 1 Gsymbol/s, 64 QAM data signal. The real-time coherent receiver consists of four 1 GS/s analog-to-digital converters (ADC) and a field-programmable gate array (FPGA) implementation. The bit error rate (BER) performance obtained with the real-time receiver is the same as that obtained with an off-line digital signal processor (DSP). This result indicates that the phase of the IF signal and the data clock timing are precisely controlled without any DSP compensations in our real-time coherent transmission system. As a result, an error free performance (BER < 1 x 10<-12>) has been achieved under a back-to-back condition. |
