• 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.
