Xining City will become a demonstration base for solar energy utilization in national buildings

The construction department of Qinghai Province requires that the solar energy utilization of buildings should be based on the advantages of solar energy resources in Qinghai Province. Based on the construction of solar energy industry bases, the introduction and digestion of domestic and foreign mature and advanced solar energy utilization technologies will accelerate the integration of solar energy buildings and the development of solar energy industry. Public buildings, affordable housing, low-rent housing, and projects involving government investment or government subsidies for government agencies and institutions should adopt solar energy technology for building and integrate solar energy with buildings.
Buildings use solar energy to gradually be extended from existing buildings to existing buildings. Large residential buildings, public buildings, and hot water consumers should actively use solar water heating systems to concentrate on solar energy. Accelerate municipal roads in urban areas, and promote the promotion of solar green lighting and solar hot water, heating in residential buildings and public buildings. Select conditional public facilities or residential communities as demonstration points for building energy conservation and solar energy utilization, and strive to build Xining City into a national demonstration base for building solar energy industrialization.

An optical fiber cable is a cable containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Different types of cable are used for different applications, for example long distance telecommunication, or providing a high-speed data connection between different parts of a building.

Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers (or fibers formed into ribbons or bundles) then have a tough resin buffer layer and/or core tube(s) extruded around them to form the cable core. Several layers of protective sheathing, depending on the application, are added to form the cable. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between the fibers, or reduces flare in fiber bundle imaging applications.
