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 fiber - Wikipedia

   en.wikipedia.org/wiki/Optical_fiber

   An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light [a] from one end to the other. Such fibers find wide usage in fiber-optic communications , where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables.

4. Fiber-optic cable - Wikipedia

   This is an accepted version of this page This is the latest accepted revision, reviewed on 19 January 2025. Cable assembly containing one or more optical fibers that are used to carry light A TOSLINK optical fiber cable with a clear jacket. These cables are used mainly for digital audio connections between devices. A fiber-optic cable, also known as an optical-fiber cable, is an assembly ...

5. Wavelength-division multiplexing - Wikipedia

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

   An intermediate line repeater is placed approximately every 80–100 km to compensate for the loss of optical power as the signal travels along the fiber. The 'multi-wavelength optical signal' is amplified by an EDFA, which usually consists of several amplifier stages. An intermediate optical terminal, or optical add-drop multiplexer (OADM ...

6. Polarization-maintaining optical fiber - Wikipedia

   en.wikipedia.org/wiki/Polarization-maintaining...

   In fiber optics, polarization-maintaining optical fiber (PMF or PM fiber) is a single-mode optical fiber in which linearly polarized light, if properly launched into the fiber, maintains a linear polarization during propagation, exiting the fiber in a specific linear polarization state; there is little or no cross-coupling of optical power ...

7. Fiber-optic sensor - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_sensor

   A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in remote sensing.
