Tellabs introduces EoSDH switch node

Fiber Optics Weekly Update, July 4, 2003

Tellabs announced a new high-density Ethernet-over-SDH switch node developed to lower telecom operators' costs by consolidating larger amounts of voice and data traffic than conventional systems. By grooming and consolidating both voice traffic and the increasing amounts of carrier-class data traffic at the network edge, the Tellabs 6345 switch node reduces the bandwidth and switching capacity needed in the core of the network, creating a truly converged network and lowering costs substantially.

The Tellabs 6345 switch node is the latest in a series of next-generation solutions from Tellabs, which enable SDH networks to transport data efficiently and cost-effectively. Products in the Tellabs 6300 managed transport series have already been deployed by leading alternate telecom operators, including Sonofon (Denmark), Tele2 (Sweden) and PGCIL (India), who typically seek to use technology to gain competitive advantage over their incumbent rivals. The new switch node, a 10 Gbit/s service platform with full Layer 2 Ethernet functionality and lower-order access, will be available for customer shipment from the fourth quarter of 2003.

The Tellabs 6345 switch node uses an Multiprotocol Label Switching (MPLS)-based Layer 2 switching that enables operators to offer true quality-of-service for data transport, while preserving the simplicity and cost-efficiency of Ethernet interfaces. It is a scalable high-density multi-service provisioning platform designed for both metropolitan and regional networks. With interfaces ranging from 2 Mbit/s to 10 Gbit/s, it provides lower-order access, integrated Fast and Gigabit Ethernet ports and full Layer 2 switching.

The new node continues the successful two-level 4/4 and 4/1 cross-connect structure introduced in the Tellabs 6350 switch node, which is well suited for implementing distributed transport switching network architectures. With a cross-connect capacity of 384 x STM-1 and 8,064 x VC-12, the Tellabs 6345 switch node is the most powerful and compact ADM-64 system on the market today. The Tellabs 6300 solution is a breakthrough next-generation SDH platform that enables network operators to deliver data efficiently and profitably. It offers integrated management of data, SDH and DWDM networks from a single network management system, enabling point-and-click network operations across network elements from the edge to the core. These leading-edge, high-density products cost-effectively collect and consolidate voice and data traffic in the metro and regional areas and are already deployed throughout Asia-Pacific, Europe, the Middle East, Africa and Latin America.
