What is the full form of SDH?
- Synchronous Digital Hierarchy
What does SDH mean?
SDH is meaning from the synchronous digital hierarchy, it is a standardized technology that is used for high-speed data transmission of telecommunication and digital signal. SDH can transfer multiple digital bit streams synchronously over the optical fiber using highly coherent light fro light-emitting diode or LASER. SDH allows data stream with low bit rates to be combined into the high rate data stream. The entire network is synchronous, individual bitstreams can be embedded into and extracted from high rate data streams relatively easily.
SDH is suitable as a transmission system for broadband ISDN and for transporting ATM cells, ethernet aggregations, SAN signals, PDH signals, and other communication signals.
