• Optical communications repeater — An optical communications repeater is used in a fiber optic communications system to regenerate an optical signal by converting it to an electrical signal, processing that electrical signal and then retransmitting an optical signal. Such… …   Wikipedia

• Optical communication — is any form of telecommunication that uses light as the transmission medium. An optical communication system consists of a transmitter, which encodes a message into an optical signal, a channel, which carries the signal to its destination, and a… …   Wikipedia

• Optical burst switching — (OBS) is an optical networking technique that allows dynamic sub wavelength switching of data. OBS is viewed as a compromise between the yet unfeasible full optical packet switching (OPS) and the mostly static optical circuit switching (OCS). It… …   Wikipedia

• Optical performance monitoring — (OPM) is used for managing high capacity dense wavelength division multiplexing (DWDM) optical transmission and switching systems in Next Generation Networks (NGN). OPM involves assessing the quality of data channel by measuring its optical… …   Wikipedia

• Optical wireless — is the combined use of optical (optical fibre) and wireless (radio frequency) communication to provide telecommunication to clusters of end points which are geographically distant. The high capacity optical fibre is used to span the longest… …   Wikipedia

• Optical Society — Type Professional organization Founded 1916 Location Washington, DC, United States Origins Founded by optical scientists in 1916 under the leadership of Perley G. Nutting Key people Christopher Dainty (President) …   Wikipedia

• Optical interferometry — combines two or more light waves in an optical instrument in such a way that interference occurs between them. Early interferometers used white light sources and also monochromatic light from atomic sources (e.g., Young s double slit experiment… …   Wikipedia

• Optical Carrier transmission rates — are a standardized set of specifications of transmission bandwidth for digital signals that can be carried on Synchronous Optical Networking (SONET) fiber optic networks.[1] Transmission rates are defined by rate of the bitstream of the digital… …   Wikipedia

• Optical Burst Switching — (OBS) is an experimental switching paradigm representing an intermediate solution between circuit (wavelength) and packet switching in optical networks. PurposeIts purpose is to dynamically provision sub wavelength granularity by optimally… …   Wikipedia

• Optical Fiber Technology — is a scientific journal that is published by Elsevier (formerly by Academic Press). Established in 1994, it covers various topics in fiber optic engineering, optical communications and fiber lasers. International Standard Serial Number: 1068 5200 …   Wikipedia
