“…In each node, the packing of logical wavelengths will then influence the choice of OADM for each stacked fibre (or band). For more details about this problem and the solution techniques proposed, we refer to [3].…”

Abstract:The dimensioning process of a multi-ring network based on optical channel shared protection is discussed. This dimensioning starts with a multi-ring routing algorithm to decide on the rings traversed by a connection, followed by "Ring Loading"-and "Logical Wavelength Assignment"-algorithms applied to the individual rings. In this paper we focus on this second aspect, for which we introduce an integrated approach. The performance and applicability of this heuristic is evaluated for different objectives.

“…To fully utilize the optical layer networks' functionality, and to achieve large capacity transmission, the use of wavelength division multiplexing have proven to be most promising (2). The use of this technology allows high speed channels to be processed optically without breaking them into lower speed electrical tributaries and enable the signals to be sent via multiple wavelength channels through a single fiber and the switching is done in granularity based wavelength channels (5).…”

This paper describes our recent approach toward advanced optical ring network through the development of optical cross add and drop multiplexer (OXADM). The OXADM prototype system focuses on providing survivability through restoration against failure, such as cable cut, in ring optical network. It features two different bandwidths which operate in working and protection line in a ring configuration. Two types of restoration scheme have been proposed to assure data flow continuously by means of linear/ multiplex protection and ring protection. The BER characteristics were measured at 2.5 Gbps (OC-48) and small degradation was observed, as confirmed by a comparison of these simulation results with those obtained from systems without restoration element. The OXADM has the same features of the conventional OADM node but with more efficiency and reliability due to internally routing mechanisms and no 'drop and re-add function' is needed to route the signal to alternative path or processed the signals in both electronic and optical domain as practice in conventional nodes today.

In this article, the characteristics, requirements and architectures of optical metropolitan area networks are presented. The main features of system offerings proposed for metro networks are also discussed. We outline our considerations about the evolution of metro area networks from SONET rings, to transparent wavelength‐routed WDM rings. We also describe the major transport impairments that limit the performance of transparent WDM metropolitan area networks and we present the characteristics of metro‐optimized optical amplifiers, fibers and optical add/drop multiplexers. Finally, we discuss recent research results that demonstrate that a properly engineered system utilizing application‐optimized components and fiber will enable the buildup of cost‐effective metro‐optimized WDM all‐optical networks.
