2. Power-over-fiber - Wikipedia

   en.wikipedia.org/wiki/Power-over-fiber

   Power-over-fiber, or PoF, is a technology in which a fiber-optic cable carries optical power, which is used as an energy source rather than, or as well as, carrying data. [ 1 ] [ 2 ] [ 3 ] This allows a device to be remotely powered, while providing electrical isolation between the device and the power supply.

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

   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. 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 ]

6. Optical power budget - Wikipedia

   en.wikipedia.org/wiki/Optical_power_budget

   The optical power budget (also fiber-optic link budget and loss budget) in a fiber-optic communication link is the allocation of available optical power (launched into a given fiber by a given source) among various loss-producing mechanisms such as launch coupling loss, fiber attenuation, splice losses, and connector losses, in order to ensure that adequate signal strength (optical power) is ...

7. Passive optical network - Wikipedia

   en.wikipedia.org/wiki/Passive_optical_network

   An optical circulator can be used for bidirectional transmission, as a type of branching component that distributes (and isolates) optical power among fibers, based on the direction of the lightwave propagation. A fiber optic filter is a component with two or more ports that provides wavelength sensitive loss, isolation and/or return loss ...
