19165 (Webpass) Google Fiber, sometimes stylized as GFiber, is a fiber broadband Internet service operated by Google Fiber Inc., [2] a subsidiary of Alphabet, [3] servicing a growing number of households in cities in 19 states across the United States. [4] In mid-2016, Google Fiber was estimated to have about 453,000 broadband customers.
Fibre-optic Link Around the Globe ( FLAG) is a 28,000-kilometre-long (17,398 mi; 15,119 nmi) fibre optic mostly- submarine communications cable that connects the United Kingdom, Japan, India, and many places in between. The cable is operated by Global Cloud Xchange, a subsidiary of RCOM. [1] The system runs from the eastern coast of North ...
Fiber (mathematics) In mathematics, the fiber ( US English) or fibre ( British English) of an element under a function is the preimage of the singleton set , [1] : p.69 that is. As an example of abuse of notation, this set is often denoted as , which is technically incorrect since the inverse relation of is not necessarily a function.
South Africa. Broadband Infraco is a South African State Owned Entity (SOE) that is intended to participate in those segments of the telecommunications market and value chain that impede private sector development and innovation in telecoms services and content offerings. Broadband Infraco maintains a national long distance fibre optic network ...
Proper morphism. In algebraic geometry, a proper morphism between schemes is an analog of a proper map between complex analytic spaces . Some authors call a proper variety over a field k a complete variety. For example, every projective variety over a field k is proper over k. A scheme X of finite type over the complex numbers (for example, a ...
Fibration. A fibration (also called Hurewicz fibration) is a mapping satisfying the homotopy lifting property for all spaces The space is called base space and the space is called total space. The fiber over is the subspace [1] : 66.
1) that, in analogy with a short exact sequence , indicates which space is the fiber, total space and base space, as well as the map from total to base space. A smooth fiber bundle is a fiber bundle in the category of smooth manifolds . That is, E , B , {\displaystyle E,B,} and F {\displaystyle F} are required to be smooth manifolds and all the functions above are required to be smooth maps ...
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. [1] [2] The light is a form of carrier wave that is modulated to carry information. [3]
