Abstract

White Rabbit (WR) technology combines gigabit Ethernet data transfer with synchronization at subnanosecond accuracy and picoseconds precision over the same fiber medium. In some applications, the WR link must maintain the synchronization accuracy over a wide temperature range. The temperature effect on a WR link is measured, and contributions from different components like optical fiber, optical transceiver, and fixed delay onboard are separately studied and analyzed. An online real-time temperature correction method is introduced to reduce the influence on synchronization accuracy of the onboard temperature variation.
