Optical Switching

Scalable optical systems for metro core and backbone applications, supporting add/drop multiplexer, broad- and wideband SDH/SONET and L2 switching functionalities from ring to meshed topologies, based on ASON/GMPLS dynamic control plane.

• 1870 Transport Tera Switch (TTS)

  • The 1870 Transport Tera Switch (TTS) is a new optical cross-connect platform providing terabit capacity and Optical Transport Network (OTN) capabilities for the next generation intelligent optical core to support scalable IP backbones.
  • Benefits include the following:
    • Solves the cost-capacity crunch, scales the IP core
      • Supports traffic growth while controlling the costs with a backbone network architecture that is highly efficient for bandwidth management, handling the traffic explosion at the most economical layer and ensuring proper power efficiency.
      • Shifts transit traffic-handling burdens away from core routers through OTN based lambda-, port- and sub-port-level IP-traffic grooming, helping reduce the cost of transport (IP offload).
      • Introduces intelligence and automation for optimizing network resources and operation—reducing TCO, ensuring the highest availability and quality assurance.
    • Maximizes bandwidth monetization
      • Cost per transported bit is reduced
      • Introduces high-level automation and intelligence that maximize reuse of available bandwidth for new traffic.
    • Simplifies operations, reduces TCO
      • Introduces GMPLS control plane intelligence for restoration and dynamic bandwidth provisioning.
      • Introduces OTN networking that ensures the transport-grade operational model of SDH/SONET is inherited, allowing for the management of any bit-rate traffic pipes with scalability up to 100G.

• 1675 Lambda Unite MultiService Switch

  • The 1675 Lambda Unite MultiService Switch is a flexible, next-generation multiservice optical switch that supports a variety of applications in both ring and mesh network topologies while keeping your network flexible, cost-effective, and easy to maintain.
  • Benefits include the following:
    • Innovative and highly flexible “any card in any slot” architecture reduces equipment types
    • Centralized non-blocking switch with flexible capacity options help to reduce floor space and operations costs
    • Multiservice support
    • Simultaneous ring and mesh support help enable future network topologies and growth

• 1678 Metro Core Connect

  • The 1678 Metro Core Connect (MCC) simplifies networks by integrating add/drop multiplexer (ADM), broadband and wideband cross-connect, and Multi-Protocol Label Switching (MPLS) functionality into a single node with a full Generalized MPLS (GMPLS) control plane. Capital expenditures can be reduced as much as 40 percent by decreasing the number of network elements required in the central office (or main exchange) while boosting network efficiency and enabling new data services.
  • Benefits include the following:
    • Facilitates flexible and cost-effective central office modernization into a single, dense node Integrates ADM, broadband, wideband and layer 2/MPLS switching capability
    • Low first cost of equipment, stemming from its modular and scalable architectural design
    • Optimizes optical infrastructure for changing service demand
    • Supports standardized GMPLS signaling for: Dynamic service provisioning, Meshed restoration, and Interoperability
