SONET/SDH Solutions

SONET/SDH (Synchronous Optical Networking/ Synchronous Digital Hierarchy) are standardized multiplexing protocols that transfer multiple digital bit streams over optical fiber.  Lower rates can also be transferred via an electrical interface.  The majority of worldwide telecom equipment is still based on legacy SONET/SDH protocols. Even though there is strong momentum to move to packet protocols, the large installed base means SONET will still be a viable player in the foreseeable future.  This maturity, as well as its inherent low overhead, makes SONET/SDH attractive to the backplane system designer.
