Optical for Wireline Carriers

Evolving Multiservice Metro Networks to Support Next-Generation Service Growth
Customer demand for increased bandwidth and new network services is growing rapidly and steadily. Industry analysts such as IDC, Infonetics Research, and Communications Industry Researchers, Inc. project that Metro Ethernet service revenue alone will surpass US$630 million by 2006 in the United States and $9.7 billion worldwide, with $7.9 billion coming from the burgeoning Asia Pacific market. Service providers that have historically relied on voice-grade networks are increasingly using IP to help enable new bandwidth-intensive services, such as Metro Ethernet and high-speed optical.

OPTIONS FOR DELIVERING IP AND ETHERNET SERVICES OVER SONET/SDH NETWORKS
The service provider market is changing rapidly as more companies adopt advanced network applications such as voice over IP (VoIP) and videoconferencing. Service providers are under mounting pressure to support the high-bandwidth, multipoint Ethernet and IP characteristics that these emerging applications require, while continuing to deliver traditional voice and data. They have two choices: They can employ the traditional time-division multiplexing (TDM) model to provide basic, Layer 1, point-to-point Ethernet circuits, or follow a more scalable multilayer approach that is capable of supporting advanced multipoint data applications.

RESILIENT PACKET RING IMPLEMENTATIONS FOR ADVANCED IP AND ETHERNET SERVICE DELIVERY
As businesses deploy more sophisticated network applications, their need for customized, high-bandwidth services is increasing. To deliver the value-added services these customers demand, service providers are rapidly integrating packet-based technologies into their metropolitan-area networks.

SECURE OPTICAL NETWORKING
Once largely the domain of service providers, optical technology is today helping numerous government and military agencies, research institutions, and enterprises to meet their growing bandwidth and availability requirements. This widespread adoption can be largely attributed to the expanded capabilities of next-generation optical platforms.

Smart Grid

Bringing the Smart Grid Idea Home
The U.S. electrical infrastructure will evolve as a highly automated and interconnected network much in the fashion of the internet; one where information and knowledge will fl ow through intelligent systems to serve the entire grid community; one where a dynamic network of smart devices enables the real-time balance of generation and delivery of electricity with the highest reliability and lowest cost. This will be accomplished while stewarding the environment in a responsible manner and enabling growth of the national economy.

Miscellaneous

Optimizing Video Transport in Your IP Triple Play Network
Service providers that compete for market share in next-generation consumer entertainment and communications services must move beyond “bundling” and offer personalized media and interactive IPTV services that blend entertainment, communications, and the Internet.

Shouldering the Weight of WiMAX [Heavy Loads Network Operators Must Bear]
WiMAX is a wunderkind technology, offering service providers a range of business models, from serving the underserved to delivering full mobile broadband to urban centers.

FLASHWAVE 4500 and FLASHWAVE 4100 MSPP Carrier-Class Ethernet Service Delivery Solutions
The FLASHWAVE® 4500 and FLASHWAVE 4100 MSPPs let service providers leverage their SONET investment to offer advanced, carrier-class Ethernet services as certified by the MEF.

Making Ethernet Over SONET Fit a Transport Network Operations Model
Many carriers deploy or evaluate deployment of EoS as a private line offering to enhance existing service offerings. Service definitions vary between carriers, but all believe the service needs to interoperate between vendors in a manner similar to current T1 or T3 services.

SMOOTHING THE TRANSITION TO IP COMMUNICATIONS
Converged networks that use IP to send data, voice, and video across a single network channel help enable greater collaboration, simplify network management, and reduce operating costs.
