Optical Transport Network — ITU T defines an Optical Transport Network (OTN) as a set of Optical Network Elements (ONE) connected by optical fibre links, able to provide functionality of transport, multiplexing, switching, management, supervision and survivability of… … 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
Channel access method — In telecommunications and computer networks, a channel access method or multiple access method allows several terminals connected to the same multi point transmission medium to transmit over it and to share its capacity. Examples of shared… … Wikipedia

Carrier scattering — Defect types include atom vacancies, adatoms, steps, and kinks which occur most frequently at surfaces due to finite material size causing crystal discontinuity. What all types of defects have in common, whether they be surface or bulk, is that… … Wikipedia
Optical hybrid — A 90° optical hybrid is a six port device that is used for coherent signal demodulation for either homodyne or heterodyne detection. It would mix the incoming signal with the four quadratural states associated with the reference signal in the… … Wikipedia
Carrier system — In telecommunication, a carrier system (loosely, a synonym with carrier) is a multichannel telecommunications system in which a number of individual channels (e.g. data, audio, video or combination thereof) are multiplexed for transmission. The… … Wikipedia
T-carrier — In telecommunications, T carrier, sometimes abbreviated as T CXR , is the generic designator for any of several digitally multiplexed telecommunications carrier systems originally developed by Bell Labs and used in North America, Japan, and Korea … Wikipedia
E-carrier — In digital telecommunications, where a single physical wire pair can be used to carry many simultaneous voice conversations by time division multiplexing, worldwide standards have been created and deployed. The European Conference of Postal and… … Wikipedia
