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 ]
The earliest basic forms of optical communication date back several millennia, while the earliest electrical device created to do so was the photophone, invented in 1880. An optical communication system uses a transmitter , which encodes a message into an optical signal , a channel , which carries the signal to its destination, and a receiver ...
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 ...
A fiber optic cable assembly with SC APC connectors, as commonly used to link optical network terminals to passive optical networks. A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment.
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]
This is the basic principle behind fiber optics in which light is guided along a high index glass core in a lower index glass cladding (Figure d). Ray optics only gives a rough picture of how waveguides work. Maxwell's equations can be solved by analytical or numerical methods for a full-field description of a dielectric waveguide.
Fiber-optic cable being pulled underneath the streets of New York City An optical fiber jack (cover removed) in a residence with FTTH service. Fiber to the premises can be categorized according to where the optical fiber ends: FTTH (fiber-to-the-home) is a form of fiber-optic communication delivery that reaches one living or working space.
