2. Fiber-optic communication - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_communication

   Fiber-optic communication is a form of optical communication for 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 ]

3. Single-mode optical fiber - Wikipedia

   en.wikipedia.org/wiki/Single-mode_optical_fiber

   In fiber-optic communication, a single-mode optical fiber (SMF), also known as fundamental- or mono-mode, [1] is an optical fiber designed to carry only a single mode of light - the transverse mode. Modes are the possible solutions of the Helmholtz equation for waves, which is obtained by combining Maxwell's equations and the boundary conditions.

4. Optical fiber - Wikipedia

   en.wikipedia.org/wiki/Optical_fiber

   These fiber optic coating layers are applied during the fiber draw, at speeds approaching 100 kilometers per hour (60 mph). Fiber optic coatings are applied using one of two methods: wet-on-dry and wet-on-wet. In wet-on-dry, the fiber passes through a primary coating application, which is then UV cured, then through the secondary coating ...

5. Passive optical network - Wikipedia

   en.wikipedia.org/wiki/Passive_optical_network

   Several fibers from an OLT can be carried in a single cable. [5] A PON reduces the amount of fiber and central office equipment required compared with point-to-point architectures with dedicated connections for every user. A passive optical network is a form of fiber-optic access network. Bandwidth is shared among users of a PON. [6] [7]

6. Fiber-optic cable - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_cable

   A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but 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 is used.

7. Internet backbone - Wikipedia

   en.wikipedia.org/wiki/Internet_backbone

   Fiber-optic communication remains the medium of choice for Internet backbone providers for several reasons. Fiber-optics allow for fast data speeds and large bandwidth, suffer relatively little attenuation — allowing them to cover long distances with few repeaters — and are immune to crosstalk and other forms of electromagnetic interference.
