Synchronous Digital Hierarchy and Wavelength Division Multiplexing

Synchronous Digital Hierarchy and Wavelength Division Multiplexing

SDH (Synchronous Digital Hierarchy) and DWDM (Dense Wavelength Division Multiplexing) are both technologies used in the field of optical networking, but they serve different purposes and operate at different layers of the network. While both enable efficient data transfer, their roles, capabilities, and applications diverge significantly. SONET employs a specific time slot structure comprising two levels: Synchronous Transport (ST) and Virtual Tributary (VT). The ST layer is used for overall bandwidth allocation, while the VT layer is utilized for finer bandwidth allocation. This tutorial addresses the importance of scalable DWDM systems in enabling service providers to accommodate consumer demand.
