SDH Multiplexer and Cross-Connect System

The FOCUS LX system is a multi-purpose synchronous digital hierarchy (SDH) multiplexer with integrated cross-connects. The system's compact size and flexibility simplify the design and use of a transport network, and can be deployed in all parts of a transport or access network. The system's main strength is in regional and metropolitan networks, where operators can use its cross-connect functionality to enhance network efficiency.

The system's architecture supports in- service upgrades. It offers add and drop multiplexing directly from 2.5 Gbps (STM-16) to 2 Mbps (VC-12) and it handles standard electrical and optical SDH, plesiochronous digital hierarchy (PDH) and ATM interfaces. In addition, its adaptive pointer filtration and resynchronization capabilities provide GSM operators with a low-jitter, 2 Mbps data line for direct base transceiver station synchronization enhancing the quality of service. The system complements FOCUS SDH and DWDM products and is managed by the FOCUS NM2100, a carrier-class network and element management system, which offers graphical network configuration and fault management.
