OTN Outperforms SONET/SDH
(pdf)
Cable operators’ Hybrid Fiber-Coax (HFC) plants pass within half a mile of some 80 percent of business locations. Therefore, extending the fiber plant to reach mid-sized to large businesses has never been easier or more rewarding. But what is the best way to aggregate, transport and switch the services for these customers?

The Value of OTN for Network Convergence and IP/Ethernet Migration
(pdf)
Today, network operaters are forced to converge their networks in order to reduce OPEX and also to eliminate unnecessary additional CAPEX on multiple parallel networks. Ciena's 4200 OTN implementation maps all services into a common set of wavelengths—simplifying everything from monitoring and deployment to sparing and capacity management.

The Network as a Programmable Service-Delivery Engine
(pdf)
Service providers face the increasing need to capitalize on the paradigm shift occurring in the ways consumers and enterprises perceive and use network services and bandwidth. To remain differentiated and valuable to end-users, providers must transition networks to service-driven and highly programmable infrastructures.

Heavy Reading White Paper: The Need for Service-Driven Networks
(pdf)
Network operators around the world are considering transforming into "next-generation telcos" to remain competitive in a drastically changing environment. This new environment presents challenges and opportunities for network operators, as well as a great deal of risk. One thing is for certain: Telecom operators that don't adapt their business models to 21st-century communications are sure to fail.

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.

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.

Infonetics White Paper: Using Carrier Ethernet to Backhaul LTE
(pdf)
LTE will become the single mobile network for mobile phone and mobile broadband, adopted by most of the world in the next five to ten years. Mobile operators and backhaul transport providers are adopting IP/Ethernet backhaul as the default technology choice to cost-effectively scale instead of relying on existing TDM-based transport networks for LTE backhaul. This paper details how Carrier Ethernet solves the challenges of LTE mobile backhaul.

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.
