IP Migration Strengthens

Majority of services become IP based Large share are at GbE & 10 GbE rates Optical transport delivers majority of IP based services WDM – a service delivery and transport vehicle

The Need for NG Optical Transport

Higher bandwidth driven by 3-play, WL data and

Business applications

Next Generation Optical (NGO or NG WDM)

The time is right for NG optical transport

New high speed interfaces (10GbE, 40G) introduced by

Data equipment

Limited flexibility, costly maintenance

Complicated operation with manual intervention

Emerging optical technologies

OTN & ASTN Standards

Key Foundations

Service adaption for legacy transport GFP/VCAT/LCAS

Modular technology convergence – WDM + TDM + Packet network elements

Dynamic optical networks (ROADM) Flexible payload over WDM – standard

optical transport (GFP + G.709 OTN) Distributed control plane (GMPLS/ASTN)


Dynamic Optics


Expectations of ROADM

“SONET like” transport Wavelength assignment & reassignment

Simplifies the planning process Removes need to predict future traffic flows

Minimize operations - OPEX savings Remote provisioning and reconfiguration Software-tunable components Automatic power balancing / Equalization

Enable complex optical topologies Subtending ring closure Multi-ring closure Mesh topologies
