Fully Digital Electronics for Fiber-Link Frequency Transfer Implemented on Red Pitaya
Abstract
This paper presents a digital instrumentation for frequency transfer on optical fiber links. The proposed system detects the phase and amplitude of the beatnotes at the two ends of the fiber for (actively or passively) compensating by the phase noise and the polarization rotation. The implementation is performed on Red Pitaya, an open source platform that integrates fast Analog-to-Digital and Digital-to-Analog converters with a Zynq System-on-Chip. The system features a detection bandwidth of 10 MHz, compatible with thousand kilometers links, that can be finely tuned for reaching an adequate Signal-to-Noise Ratio minimizing the generation of cycle slips.
