  As the development of electronic science and technology, electronic data
acquisition (DAQ) system is more and more widely applied to nuclear physics
experiments. Workstations are often utilized for data storage, data display,
data processing and data analysis by researchers. Nevertheless, the
workstations are ordinarily separated from detectors in nuclear physics
experiments by several kilometers or even tens of kilometers. Thus a DAQ system
that can transmit data for long distance is in demand. In this paper, we
designed a DAQ system suitable for high-speed and high-precision sampling for
remote data transfer. An 8-channel, 24-bit simultaneous sampling
analog-to-digital converter(ADC) named AD7779 was utilized for high-speed and
high-precision sampling, the maximum operating speed of which runs up to 16
kilo samples per second(KSPS). ADC is responsible for collecting signals from
detectors, which is sent to Field Programmable Gate Array(FPGA) for processing
and long-distance transmission to the workstation through optical fiber. As the
central processing unit of DAQ system, FPGA provides powerful computing
capability and has enough flexibility. The most prominent feature of the system
is real-time mass data transfer based on streaming transmission mode, highly
reliable data transmission based on error detection and correction and
high-speed high-precision data acquisition. The results of our tests show that
the system is able to transmit data stably at the bandwidth of 1Gbps.
