Ethernet is used as networking technology for frame-based computers. Ethernet is mostly used for Local the physical components of the OSI model for networking through the use of Media Access Control (MAC) via the layer of the Datalink. SDH, on the other hand, is the acronym for Synchronous Digital Hierarchy. SDH is a kind of technology for data transmission via optical media. SDH provides a very quick and less expensive data connection or transmission.
It ensures the transfer of multiple numbers of digital bit via optical media by using light-emitting diodes. Ethernet can be used to connect the network and the different systems that are within its area of reach. SDH was created to increase the work of a technology known as Plesiochronous Digital Hierarchy for superior data transmission so as to reduce the possible occurrence of synchronization problems.
