In this article we will discuss Optical Transport Network, will make brief discussion on Optical Transport Network, In last article we discuss about PON.
Optical transport network (OTN) is a series of standards created to combine the benefits of SONET/SDH with the bandwidth-expanding capabilities of Dense Wave Division Multiplexing (DWDM) in order to build more network functionality into optical networks.
The OTN frame is very similar to a SONET frame in its structure and format. There are three overhead areas in an OTN frame: the Optical Payload Unit (OPU) overhead, the Optical Data Unit (ODU) overhead, and the Optical Transport Unit (OTU) overhead.
Cellphones work a different way: they send and receive information using invisible radio waves—a technology called wireless because it uses no cables. Fiber optics works a third way. It sends information coded in a beam of light down a glass or plastic pipe.
The optical transport network (OTN) and WDM layers make up a generic Layer-1 transport network, enabling different service types to coexist and share the same infrastructure transparently, without affecting each other’s performance.
The OTN does not require any synchronization functionality. The OTN – specifically the mapping/demapping/desynchronizing and multiplexing/demultiplexing processes and justification granularity information – is designed to transport synchronous client signals, like synchronous STM-N and synchronous Ethernet signals.
I am Hamza arif, and i am excited to learn new things, i am well focused for my work and always try to explore new things. My graduate is in BS (Telecom) and i am expert in Networks and working on new technology is my passion i work a lot on AI (Artificial Intelligence) Augmented Reality and many other projects.
