What is main difference in PDH and SDH Tech...

Answer / jagadesh

PDH AND SDH ARE TWO SYSTEMS OF TRANSMISSION USED IN COMMUNICATION THROUGH MICROWAVE RADIO AND FIBER OPTIC SYSTEMS.
PLESIOSCHRONOUS DIGITAL HIERARCHY (PDH)SYSTEM IS USED WHERE LOWER CAPACITY OF E1 HAS TO BE TRANSMITTED SAY UPTO 16E1 G.703.
THIS PDH SYSTEM IS USED ESPECIALLY FOR POINT TO POINT SHORT HAUL TRANSMISSION.

SYNCHRONOUS DIGITAL HEIRARCHY(SDH) SYSTEM IS USED FOR HIGHER CAPACITY TRANSMISSION SAY UPTO STM4.THIS SDH SYSTEM IS USED ESPECIALLY FOR LONG HAUL TRANSMISSION.
