2. Fiber-optic communication - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_communication

   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] Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to ...

3. 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.

4. Optical Carrier transmission rates - Wikipedia

   en.wikipedia.org/wiki/Optical_Carrier...

   Optical Carrier transmission rates are a standardized set of specifications of transmission bandwidth for digital signals that can be carried on Synchronous Optical Networking (SONET) fiber optic networks. [1] Transmission rates are defined by rate of the bitstream of the digital signal and are designated by hyphenation of the acronym OC and an ...

5. 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 ...

6. Multi-mode optical fiber - Wikipedia

   en.wikipedia.org/wiki/Multi-mode_optical_fiber

   Multi-mode optical fiber. Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multi-mode links can be used for data rates up to 800 Gbit/s. Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits ...

7. Broadband - Wikipedia

   en.wikipedia.org/wiki/Broadband

   Broadband. Fixed broadband subscriptions (per 100 people) In telecommunications, broadband or high speed is the wide- bandwidth data transmission that exploits signals at a wide spread of frequencies or several different simultaneous frequencies, and is used in fast Internet access. The transmission medium can be coaxial cable, optical fiber ...
