SDH Multiplexer

SDH Multiplexer

SDH (Synchronous Digital Hierarchy) is an international standard for high speed telecommunication (STM-1, STM-4, STM-16) over optical/electical networks which can transport digital signals in variable capacities. It is a synchronous system that intend to provide a more flexible, yet simple network infrastructure. SDH multiplexer is a device that provides both transport and access capabilities for voice, data, IP/Ethernet WAN, video and utility teleprotection traffic in a single package.
