SONET/SDH Insights

What is SONET/SDH?

SONET (Synchronous Optical Network) and SDH (Synchronous Digital Hierarchy) are standardized digital communication protocols used to transport high-bandwidth data over optical fiber. They are commonly used in telecommunications networks to provide reliable and efficient transmission of voice, data, and video signals.
