21Optical isolator — This article is about the optical component. For the optoelectronic component, see Opto isolator. An optical isolator, or optical diode, is an optical component which allows the transmission of light in only one direction. It is typically used to …
22Laser hélium-néon — Un laser hélium néon est un laser à gaz de petite dimension. Il a de nombreuses applications scientifiques et industrielles, on l utilise aussi au laboratoire pour les démonstrations d optique. Il émet dans le rouge sur 632,8 nm… …
23Optical power margin — In an optical communications link, the optical power margin is the difference between the optical power that is launched by a given transmitter into the fiber, less transmission losses from all causes, and the minimum optical power that is… …
24Optical microcavity — An optical microcavity is a structure formed by reflecting faces on the two sides of a spacer layer or optical medium. The name microcavity stems from the fact that it is often only a few micrometers thick, the spacer layer sometimes even in the… …
25Synchronous optical networking — (SONET) and Synchronous Digital Hierarchy (SDH), are two closely related multiplexing protocols for transferring multiple digital bit streams using lasers or light emitting diodes (LEDs) over the same optical fiber. The method was developed to… …
26Automatic Laser Shutdown — Automatic Laser Shutdown, or ALS, is a method for assuring Laser safety in Optical Transmission Systems (Like optical SDH) registered under US Patent #6194707.ALS is a semi intelligent method which cuts the Tx line if the Rx line is inactive, and …
27Electric power transmission — Electric transmission redirects here. For vehicle transmissions, see diesel electric transmission. 400 kV high tension transmission lines near Madrid Electric power transmission or high voltage electric transmission is the bulk transfer of… …
28Noise-immune cavity-enhanced optical heterodyne molecular spectroscopy — (NICE OHMS) is an ultra sensitive laser based absorption technique that utilizes laser light to assess the concentration or the amount of a species in gas phase by absorption spectrometry (AS). Contents 1 Principles 1.1 Types of signals 1.2… …
29Noise-Immune Cavity-Enhanced Optical-Heterodyne Molecular Spectroscopy — (NICE OHMS) is an ultra sensitive laser based absorption technique that utilizes laser light to assess the concentration or the amount of a species in gas phase by absorption spectrometry (AS). Principles The NICE OHMS technique combines in a… …
30Multi-mode optical fiber — A 1.25 Gbit/s multi mode fiber Multi mode optical fiber (multimode fiber or MM fiber or fibre) is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Typical multimode links… …
