Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH) are standardized protocols that transfer multiple digital bit streams synchronously over optical fiber using lasers or highly coherent light from light-emitting diodes (LEDs). At low transmission rates data can also be transferred via an electrical interface. The method was developed to replace the plesiochrono… WebbSTM frame structure,SDH Signal Mapping, Heirarchy Mapping, STM mapping from 2 Mbps, Plesiochronous Digital Hierarchy (PDH), SDH :- synchronous Digital Hierar...
