Synchronous Digital Hierarchy (SDH) are standardized protocols thattransfer multiple digital bit streams synchronously over optical ber.

The basic unit of framing in SDH is a STM! (Synchronous TransportModule" level !)" #hich operates at !$$.$%& megabits per second (Mbit's).

STM! carries %! !

Dense #avelength division multiple*ed (D+DM) system can be vie#ed as aparallel set of optical channels" each using a slightly di,erent #avelength"but all sharing a single transmission medium.
