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. Optical networking - Wikipedia

   en.wikipedia.org/wiki/Optical_networking

   Optical networking is a means of communication that uses signals encoded in light to transmit information in various types of telecommunications networks.These include limited range local-area networks (LAN) or wide area networks (WANs), which cross metropolitan and regional areas as well as long-distance national, international and transoceanic networks.

4. 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.

5. Optical fiber - Wikipedia

   en.wikipedia.org/wiki/Optical_fiber

   Attenuation in fiber optics, also known as transmission loss, is the reduction in the intensity of the light signal as it travels through the transmission medium. Attenuation coefficients in fiber optics are usually expressed in units of dB/km. The medium is usually a fiber of silica glass [f] that confines the incident light beam within ...

6. Wavelength-division multiplexing - Wikipedia

   en.wikipedia.org/wiki/Wavelength-division...

   In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. [1]

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.

   Fibre Channel director with SFP+ modules and LC optical fiber connectors with Optical Multimode 3 (OM3) fiber (aqua) Fibre Channel switches can be divided into two classes. These classes are not part of the standard, and the classification of every switch is a marketing decision of the manufacturer:
