LOGO principlecoherent transmission systemline with chromatic dispersion compensatorsWe discuss the design issues and characteristics of coherent fibre-optic communication networks taking into account the many physical effects that simultaneously influence signal propagation. Algorithms and easy-to-use '...
The integration of high-speed optical communication and distributed sensing could bring intelligent functionalities to ubiquitous optical fibre networks, such as urban structure imaging, ocean seismic detection, and safety monitoring of underground embedded pipelines. This work demonstrates a scheme of integra...

In order for the fiber-optic raster match back in the system to achieve fiber-optic raster weak signal detection and processing, the application of photovoltaic (PV) weak signal detection principle on the basis of the design of a high signal-to-noise measurement accuracy higher than the back-...
Another significant advantage of office reporting and analytics is the ability to drive better communication and collaboration within organizations. With the availability of real-time data and easy-to-understand reports, employees and managers across departments can stay informed about the company’s perfo...
2, the principle of FBG sensor is to form a narrow-band (transmission or reflection) filter or mirror in the fiber core, and monitor the numerical changes of specified physical quantities through the changes of incident wavelength and reflected wavelength of light. Fiber Bragg grating sensors, ...
The large development of fibre Bragg gratings (FBGs) over decades has made this kind of structures one of the most mature optical fibre sensing technologies existing today, demonstrating key features for a very wide range of applications. FBG sensors are fragile and must be normally protected for...
Fig. 1: Principle of the proposed coding and decoding process. The upper row shows the procedure to generate an Nc-point discrete-time signal c(n) representing the digitally coded pulse sequence from a Nu-point unipolar sequence u(n). This procedure involves three steps: (1) generate an Np...
