Transoceanic Phase and Polarization Fiber Sensing using Real-Time Coherent Transceiver

Detection of hydroacoustic signals on a fiber-optic submarine cable
Although the study suggests that virtual sensor’s self-noise of the present DAS measurement is relatively high compared to the conventional in-situ hydroacoustic sensors above a few Hz, the DAS identifies the ocean microseismic background noise along the entire submarine cable except for some cable sections de-coupled from the seafloor.

Optical polarization–based seismic and water wave sensing on transoceanic cables
The polarization of regular telecommunication traffic is used to detect earthquakes and water swells in a 10,000-kilometer-long fiber-optic submarine cable (see the Perspective by Wilcock) and is highly scalable for converting global submarines into continuous real-time earthquake and tsunami observatories.

Distributed acoustic sensing for seismic activity monitoring
Early approaches on the application of fiber-optic distributed acoustic sensors (DASs) for seismic activity monitoring are discussed and new experimental results on teleseism monitoring based on a specific approach: the so-called chirped-pulse DAS are illustrated. Expand
Distributed optical fiber pressure sensors
Abstract The measurement of pressure by using distributed optical fiber sensors has represented a challenge for many years. While single-point optical fiber pressure sensors have reached a solidExpand
Distributed sensing of earthquakes and ocean-solid Earth interactions on seafloor telecom cables

Illuminating seafloor faults and ocean dynamics with dark fiber distributed acoustic sensing
Distributed fiber-optic sensing technology coupled to existing subsea cables (dark fiber) allows observation of ocean and solid earth phenomena and highlights this method’s potential for marine geophysics. Expand
SMART Cables for Observing the Global Ocean: Science and Implementation
Simulations show that deep ocean temperature and pressure measurements can improve estimates of ocean circulation and heat content, and cable-based pressure and seismic-acceleration sensors can improve tsunami warning times and earthquake parameters. Expand
Optical frequency transfer over submarine fiber links
Bidirectional phase-stabilized optical fiber links allow state-of-the-art optical clocks to be compared on a continental scale. However, intercontinental comparisons are still based on satelliteExpand
Ultrastable laser interferometry for earthquake detection with terrestrial and submarine cables
It is found that ordinary submarine telecommunication cables can be used to detect earthquakes, and existing telecommunication optical fiber cables can detect seismic events when combined with state-of-the-art frequency metrology techniques by using the fiber itself as the sensing element. Expand
Polarization-Related Statistics of Raman Crosstalk in Single-Mode Optical Fibers
We present a novel comprehensive theory for the pump-to-probe interactions caused by the stimulated Raman scattering (SRS) in glass optical fibers. The developed theory applies to both the Raman gainExpand
