摘要

本文演示了一种基于光纤的星形频率传播系统。通过被动消除远端相位噪声，简化了本端配置。从而提高了系统的可扩展性。此外，设计了双混频器装置，消除了混频器隔离有限导致的射频泄漏，大大提高了传播系统的长期稳定性。在50公里光纤链路上，相对频率稳定性在1秒达到1.35 × 10−14，在104秒达到6.32 × 10−17。该方案提供了一种简单的多址频率传输方法，在频率分配网络中具有很大的应用潜力。

Simple method for multi-access frequency transfer with remote passive phase noise compensation

In this paper, we demonstrated a star-shaped frequency dissemination system based on fiber optic. By passively eliminating the phase noise at the remote end, we simplified the configuration of the local end. So that the scalability of the system had been improved. In addition, a dual-mixer device was implemented to eliminate the RF leakage caused by the limited isolation of the mixer, which greatly improves the long-term stability of the dissemination system. The relative frequency stability reaches 1.35 × 10⁻¹⁴ at 1 s and 6.32 × 10⁻¹⁷ at 10⁴ s over a 50 km fiber link. Our scheme provides a simple method for multi-access frequency transfer, which has great potential in frequency distribution network.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
