What Is OTN Network—Optical Transport Network?
With the explosion of digital traffic and the ever-growing array of bandwidth-hungry applications, Optical Transport Network (OTN) evolves from point-to-point DWDM remedies to scalable and robust optical networking applications that cater to a wide variety of client signals with equally-varied service requirements. Carriers are also placing a particular emphasis on OTN in the Metro area, where it is shifted rapidly from SONET/SDH to wavelength-division multiplexing (WDM). With the goal of boosting bandwidth and increasing network functionality, OTN provides a way to support different traffic types in a more cost-effective manner than by using SONET/SDH networks. What Is OTN Network？ Defined by the ITU Telecommunication Standardization Sector (ITU-T), OTN is a digital wrapper technology that provides an efficient and globally accepted way to multiplex different services onto optical light paths. The OTN technology or digital wrapper technology provides a network-wide framework that add...
