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?

Carrier Ethernet: Taking Bandwidth to the Edge
(pdf)
As demand explodes for voice, video and data services, and as the number of users of those services surges, government agencies are taxed with finding ways to cost-effectively get as much bandwidth as possible to the users at the network edge. Faced with the need to upgrade their network infrastructures, agencies are opting to move away from aging TDM technologies such as ATM. One new method rapidly attracting organizations is Carrier Ethernet.

(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.

Solving the 100 Gb/s 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.
