Signal regeneration
Encyclopedia
In telecommunications, signal regeneration is signal processing
that restores a signal
, recovering its original characteristics.
The signal may be electrical, as in a repeater
on a T-carrier
line, or optical
, as in an OEO optical cross-connect
.
Signal processing
Signal processing is an area of systems engineering, electrical engineering and applied mathematics that deals with operations on or analysis of signals, in either discrete or continuous time...

Signal (electrical engineering)
In the fields of communications, signal processing, and in electrical engineering more generally, a signal is any time-varying or spatial-varying quantity....

Repeater
A repeater is an electronic device that receives asignal and retransmits it at a higher level and/or higher power, or onto the other side of an obstruction, so that the signal can cover longer distances.-Description:...

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 South Korea....

Optical communication
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 receiver, which reproduces the...

Optical cross-connect
An optical cross-connect is a device used by telecommunications carriers to switch high-speed optical signals in a fiber optic network, such as an optical mesh network.There are several ways to realize an OXC:...
