What is telecommunication transmission?
In telecommunications, transmission is the process of sending and propagating an analog or digital signal using a wired, optical, or wireless electromagnetic transmission medium. Examples of transmission are the sending of signals with limited duration, for example, a block or packet of data, a phone call, or an email.
What is PTN equipment?
It is a manageable and reliable bearer technology offering the bandwidth flexibility to carry multiple services. PTN equipment has the following features: PTN, a connection-oriented transport network technology, has been developed to solve these problems.
What is optical transport equipment?
ITU-T defines an Optical Transport Network as a set of Optical Network Elements (ONE) connected by optical fiber links, able to provide functionality of transport, multiplexing, switching, management, supervision and survivability of optical channels carrying client signals.
Where is Sonet used?
Both SDH and SONET are widely used today: SONET in the United States and Canada, and SDH in the rest of the world. Although the SONET standards were developed before SDH, it is considered a variation of SDH because of SDH’s greater worldwide market penetration.
What is Roadm in telecom?
A reconfigurable optical add-drop multiplexer (ROADM) is a device that can add, block, pass or redirect modulated infrared (IR) and visible light beams of various wavelengths in a fiber optic network. ROADMs are used in systems that employ wavelength division multiplexing.
