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.

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.

Maximizing LTE Benefits Using True Carrier Ethernet Backhaul
(pdf)
Mobile Network Operators are evolving their wireless infrastructure to the Long Term Evolution (LTE) standard that offers low latency and high bandwidth to deliver rich content to smart mobile devices. This paper articulates the challenges and complexities in LTE design with the recommendation to use Carrier Ethernet-based solutions for backhaul from cell sites to reduce TCO. Backhaul providers can use this approach to scale their networks cost-effectively. Finally, this paper describes Ciena’s solution, which combines True Carrier Ethernet-based cell site demarcation with converged optical Ethernet aggregation to build scalable cost-effective networks.

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.

Relever le défi de la transmission 100 Gb/s
(pdf)
Alors que les débits de transmission passent de 10 Gb/s à 40 Gb/s et vont jusqu’à 100 Gb/s, il devient de plus en plus compliqué de respecter les mêmes paramètres de performances que ceux auxquels les prestataires de services sont accoutumés à 10 Gb/s et qui ont contribué à la réduction significative des dépenses d’investissement et d’exploitation à l’échelle du réseau. Les prestataires de services qui choisissent de déployer une solution 40G cohérente de Ciena peuvent faire évoluer leurs réseaux pour ajouter des longueurs d’ondes de 100 Gb/s dès que leur activité l’exige, mettant ainsi en œuvre la technologie 100 Gb/s sur leurs réseaux existants avec des attributs de transmission similaires à ceux actuellement permis.

Packet Transport Evolution
(pdf)
When it comes to packet transport, one single solution is hardly an answer for all carriers’ needs, given the diversity of their subscribers’ requirements and the legacy of their installed base. In addition to the cost of the solution, packet transport also must address the transparency and the unique characteristics of the transport network. Ciena’s Intelligent Infrastructure allows the combination of several transport technologies—including Coherent 40G/100G and 1T—to provide a complete toolset for the most efficient and comprehensive packet transport architecture, with the agility, efficiency, and cost-effectiveness suited for carrier needs for years to come.
