Optical communication, also known as optical telecommunication, is communication at a distance using light to carry information. It can be performed visually or by using electronic devices.

chapter introduces optical communications and applications of photonics in Section 12.1. It then discusses simple optical waveguides in Section 12.2, lasers in Section 12.3, and representative components of optical communications systems in Sections 12.4, including photodetectors in 12.4.1-2, multiplexers in 12.4.3, interferometers in 12.4.4 ...

Optical communication systems transmit information optically through fibers. This is done by converting the initial electronic signals into light pulses employing laser or light-emitting diode light sources. The light launched at one end of an optical fiber is confined to the fiber core and propagates along it over long distances.

2023年9月20日 · Optical spectrum uses light as a means of transmitting information via lasers. Optical communications benefits include being faster, more secure, lighter and more flexible. Optical communications challenges include a need for precise laser beam accuracy and Earth’s atmosphere interference, such as clouds.

Optical communication uses infrared light "" C band is used commonly because of EDFAs. Graded index fiber has a lower modal dispersion than step index fiber ""Plastic fiber is cheaper than glass fibers Dispersion shifted fiber is used in DWDM systems If a signal can travel 1600 km at 10 Gbps, due to PMD it can travel 400 km at 40 Gbps

Optical networking is a means of communication that uses signals encoded in light to transmit information in various types of telecommunications networks.
