Fiber-delay measurement is one of the key fundamental technologies in numerous fields.
Here, we propose and experimentally demonstrate a high-precision and concise optical time …

Distributed RF systems are referred to as the fundamental structure for future wireless
communication and sensors. To enable wideband coherent operation, synchronization …

The propagation distance confines the development of precise time-frequency transmission
using optical frequency combs due to the dispersion of the link. Here we disseminate a fiber …

Time transfer based on phase modulation schemes has attracted extensive attention in
recent years. We propose and experimentally demonstrate an adjustable and stable …

The non-reciprocal and dynamic nature of polarization mode dispersion (PMD) in optical
fibers can be a problem for accurate time and frequency transfer. Here, a simple, passive …

A simple scheme for all-optical time interpolation using spectral interferometry is put forward
that is, in principle, capable of single-shot measurements. In this method, the arrival time of …

In the paper, we design a monitoring and management system (MMS) for optical fiber time
transfer (OFTT) based on manager/agent model. The proposed system includes monitoring …

Critical infrastructures are becoming increasingly dependent on accurate and continuous
position, navigation, and timing (PNT) services provided by Global Navigation Satellite …
