OFC 2003 workshop on wavelength selective switching based optical networks

This paper provides an overview of OFC 2003 Workshop on Wavelength Selective Switching Based Optical Networks, from the perspective of the co-organizers. The Workshop was held on Monday 24 March 2003.

Sprint long distance network survivability: today and tomorrow

The high reliability exhibited by the Sprint long distance network is the result of many interrelated factors. The network utilizes robust architectures, systems, and equipment to provide a reliable transport infrastructure. Redundant equipment, conservative synchronization, protected power, and other factors combine to form a dependable foundation. New architectures and systems are under development to meet the changing demands of customers. This article summarizes Sprints current network reliability, and emerging demands and technology, and presents possible directions for the future Sprint network. Sprint selected the SONET four-fiber bidirectional line switched ring (4F BLSR) architecture for the vast majority of its transport network architecture. A 4F BLSR architecture requires four fibers, or four optical wavelengths of wave division multiplexing (WDM), to accommodate a work and protect path in each direction around a ring of network elements or add-drop multiplexers (ADMs).

Optical networking standards

Optical networking standards are being developed to facilitate global interoperability of optical services. They are being drafted, approved, and implemented in every area of the telecommunications industry. To maximize ones value from the standards, one should understand the standards organizations involved, the opportunities for participation, and the strategies for successful contributions. This paper presents an overview of these aspects to stimulate thought and to encourage participation in the standards development process.Summary form only given. This tutorial will survey optical networking industry standards, the organizations where they were developed, and the processes and procedure by which those organizations operate.

OC-48/STS-48c IP direct on wavelength application

Synchronization, protection, restoration, and architecture are described for a direct on wavelength IP application. Interfaces for direct connection to dense wavelength-division multiplexing equipment are defined and experimental results for a 20,000-km transmission experiment are presented.

Attributes of the Next Generation Sprint Optical Transport Network

The telecommunications optical network layer has many definitions and many different applications. The Sprint optical network definition continues to evolve with the technology and customer demands. New technology advances and progress in standards are opening a window into a vastly enhanced optical layer. Optical networking may soon be possible and practical for a long distance network spanning the size of the United States. Sprint is studying the options for the optical layer and its boundaries. This paper discusses some of the attributes of a future Sprint optical network.
