DWDM

The demand for greater bandwidth generally creates a need for increased network capacity. The telecommunications industry has responded to this demand with the design and deployment of new DWDM (dense wavelength division multiplexed) and high bit rate TDM (time division multiplexed) optical transport systems with capacities from 40 Gbps to 1.6 Tbps. These higher bit rates and narrower spaced channels make it necessary to examine impairments such as continuity, dispersion, and distortion, in order to qualify network performance, especially in uncharacterized and/or non-standard plants. In this paper, methods and procedures for the characterization of fiber optic networks are developed, data and results from field experiences are described, and the effect and impact on typical network configurations are discussed. tech news

Compared to earlier, time-division multiplexing (TDM) products, the Cisco ONS 15454 Multiservice Provisioning Platform (MSPP) represented a new network element option consisting of tightly integrated circuit and packet service interfaces with centralized cross-connect and management features, paving the way to any location-to-any location (or what is called "A to Z") circuit provisioning. This feature set enabled service providers to deploy higher-revenue data services more quickly and efficiently than ever before. Today, the higher integration and provisioning standards pioneered by the Cisco ONS 15454 MSPP are widely deployed and commonly accepted as mandatory for all metro optical platforms. tech news

DWDM systems must operate in an ideal environment to maintain reliable and very high service availability. In addition to high bandwidth, bandwidth service providers must provide visibility into their system to their most demanding and educated customers, who have to support a large community of end-users. These end-users now expect high bandwidth services at all times, under any conditions and will not tolerate any performance degradations. This paper briefly discusses how Netcool/OMNIbus solutions meet these challenges. tech news

The landscape of the Access network has undergone tremendous change in recent years. Services at the edge have increased in diversity and complexity while Carriers are forced to keep their eyes on the economics of deployment on investment protection. In this landscape, the access network is a key revenue-generating resource for service providers, and efficiency in service delivery is the key to profitability. This white paper looks briefly at an alternate view to building and maintaining network vitality - one that builds on the existing infrastructure to create a solution today with a vital growth path into the future. tech news
