本文介绍了一种用于数字化光纤无线电（DROF）系统的硬件实现网络时间协议（HwNTP）模块的同步性能。在实验中，HwNTP客户端通过异步分组网络与HwNTP服务器同步，并且与基于软件的NTP相比提供高度精确的时间和频率参考。在商业以太网服务上实现的精度足以满足DROF要求。
: This paper reports on the synchronization performance of a hardware implemented network time protocol (HwNTP) module for digitized radio over fiber (DROF) system. In the experiments, the HwNTP client is synchronized with the HwNTP server via an asynchronous packet network, and provides highly accurate time and frequency references compared to software based NTP. The achieved accuracy over a commercial Ethernet service is sufficient to satisfy the DROF requirements.
