A Study on Sonet and SDH with their Defects in Optical Network

摘要

Background Objectives: Data transmission over a communication channel, should provide important facilities to be added, including data framing, error checking and to manage the channel. Methods/Stastical Analysis: This is a complete review paper and theoretically we intend to explain the basics of SONET / SDH, Architecture, Bit rates, Netowork configurations etc. All these are standardised and approved by ANSI. Conclusion: One would get to know what Synchronous Optical Network / Synchronous Digital Hierarchy (SONET/SDH) is all about and how exactly are they used through this paper. Also, the merits and de-merits are completely analysed.
