SDH Network Access

Facing increasingly complex demands for communications and security, organizations are looking for cost effective, reliable solutions for managing mission critical operations. The robust design of the GE Lentronics TN1U SDH Multiplexer makes it the ideal optical networking solution for electric power utility, transportation, pipeline and many industrial requirements.

System Technology

This powerful SDH multiplexer has a modular design for ease of maintenance, configuration flexibility, and expandability.

SDH Network Flexibility

Simply replacing optical transceiver modules allows users to expand an existing TN1U system to a higher capacity, while maintaining their capital investment.

The optional CDAX module provides an integrated digital cross-connect for grooming 64 kb/s channels and optimizing tributary payloads.

Operations, Administration, Maintenance and Provisioning (OAM&P)

The TN1U takes advantage of the inherent network management capabilities provided by the SDH telecommunications standards.
