SDH/SONET Insights

What is SDH/SONET?

SDH/SONET are standardized digital communication protocols used to transport high-bandwidth data over optical fiber. SDH (Synchronous Digital Hierarchy) is the ITU-T standard, while SONET (Synchronous Optical Network) is the ANSI standard. They are commonly used in telecommunications networks to provide a robust and reliable infrastructure for transmitting voice, data, and video signals.
