About the Alcatel 1641 DS

The Alcatel 1641 DS is a compact, high-performance SDH (Synchronous Digital Hierarchy) Add-Drop Multiplexer designed to meet the growing demands of modern transmission networks. Part of the trusted Alcatel-Lucent 1600 Series, the 1641 DS delivers robust and flexible transport capabilities, making it ideal for metropolitan and regional networks where efficient bandwidth management and service scalability are essential.

Engineered to support STM-1 and STM-4 transmission rates, the 1641 DS enables the seamless aggregation, grooming, and delivery of digital signals with carrier-grade reliability. Its modular design allows for a variety of tributary interfaces, including E1, E3, DS3, and Ethernet, ensuring compatibility with both legacy systems and emerging IP-based services.

With features such as integrated cross-connect functionality, advanced alarm monitoring, and network management support via Q3 and SNMP protocols, the Alcatel 1641 DS offers a future-ready solution for operators seeking to optimize transport efficiency while maintaining service quality.

  • Fully compliant with ITU-T standards including G.707, G.783, G.803, and G.957

  • Offers both optical and electrical transmission interfaces for versatile deployment

Broad Interface Support

The system supports a variety of tributary interfaces, enabling seamless integration with legacy and modern network elements.

  • E1 (2 Mbps) tributary interfaces for traditional PDH services

  • E3 and DS3 interfaces for higher-capacity PDH connections

  • 10Base-T and 100Base-T Ethernet interfaces for basic packet-based services

  • STM-1 optical/electrical interfaces and STM-4 optical interfaces

Advanced Cross-Connect and Grooming

Efficient bandwidth management is achieved through a fully non-blocking cross-connect matrix that allows for fine-grained grooming at multiple virtual container levels.

  • VC-12, VC-3, and VC-4 granularity switching

  • Dynamic add/drop and pass-through capabilities for flexible traffic routing

  • Enables service multiplexing and grooming at both low and high speeds

Support for Diverse Network Topologies

The 1641 DS can be deployed in various topologies, offering service providers flexibility in building and maintaining their transport networks.
