Similarly, what are the advantages of SDH over PDH?

3.SDH Advantages over PDH The advantages enjoyed by utilization of SDH includes: (1)The standardized optical interfaces make it very convenient for interconnection in lines. (2)The world-standard frame structure and rate of digital signals make it easy to interconnect in the world. (3)SDH has excellent ability of DXC.

Where is SDH used?

Both SDH and SONET are widely used today: SONET in the United States and Canada, and SDH in the rest of the world. Although the SONET standards were developed before SDH, it is considered a variation of SDH because of SDH's greater worldwide market penetration.
