A Comparison of Next-generation 40-Gbps Technologies (pdf)
There are many proposed optical transmission systems that offer 40 Gb/s wavelength capacity. The unbridled adoption of these solutions may well depend on the degree to which they overlay on existing DWDM 10 Gb/s links. This paper provides a description of new 40 Gb/s technologies being proposed and reveals their true compatibility with existing 10 Gb/s infrastructure.

Solving the 100G Transmission Challenge (pdf)
As the line transmission rates are increased from 10 Gb/s to 40 Gb/s to 100 Gb/s, it becomes increasingly challenging to meet the same system performance parameters that service providers are accustomed to at 10Gbps that have helped dramatically reduce network-level CAPEX and OPEX. Service providers deploying a Ciena 40G coherent solution can evolve their networks to add 100 Gb/s wavelengths as soon as their business dictates, deploying 100 Gb/s on their existing network with similar transmission attributes as those currently allowed today.

Heavy Reading White Paper: Building the Next-Generation Packet-Optical Switching Network (pdf)
The next phase of SONET/SDH to packet network migration is underway, and optical networks must evolve to meet the challenges. To do this, a renewed focus has been placed on optical switching innovations and a tighter coupling of switching and transport through element integration and a unified control plane. Meanwhile, the network must continue to support legacy SONET/SDH traffic. Also, the network and network elements must have a high degree of modularity so operators can add the features and functions they need, when they need them.

The Intelligent Path to a Service-Enabling Infrastructure (pdf)
The rise in bandwidth demand represents an era of major change in the ways residential and business services are used, sold, and supported on the network. To truly address the financial and technological imperatives of a network operator’s business, a more customizable and optimized approach to switching is required—one that provides a degree of hardware and software modularity and reconfigurability not found in today’s solutions. This new switching flexibility, made possible with a reconfigurable approach, will allow network operators to achieve a service-enabling switching infrastructure that can help drive top-line revenues, decrease costs, and ultimately differentiate offered services to achieve a sustainable competitive advantage.

FlexSelect Architecture: Achieving Profitability and Convergence (pdf)
IP and Ethernet packet services are a growing part of the network traffic load, but service providers must continue to support legacy services. Customers cannot be forced to move to packet-based services before they are ready. It makes financial sense for service providers to extend their existing networks to support packet traffic rather than to overlay them with a new network.

Ovum RHK White Paper: OTN Emerges as a Must Have (pdf)
OTN, the Optical Transport Network, dates back to 1998, but is only now hitting its stride as a requirement for next-generation optical network elements. OTN was one of many promising optical technologies whose rollout was delayed by post-bubble investment declines. As network operators have begun spending again, and as service bandwidths and transport pipes are getting larger, OTN has reemerged as a “must have” technology, but not for the lofty reasons many often cite.
