A case study of a WDM agent

Integrated Network Management VI. Distributed Management for the Networked Millennium. Proceedings of the Sixth IFIP/IEEE International Symposium on Integrated Network Management. (Cat. No.99EX302), 2003
This paper presents a case study of the development of a WDM agent for the control of two prototype photonic network elements, an optical add/drop multiplexer and an optical cross-connect. Even though the hardware developed for these prototypes is too small for a commercial device, the software is fully featured, and with modifications, could support ...

Parametric gain in WDM systems

1999 IEEE LEOS Annual Meeting Conference Proceedings. LEOS'99. 12th Annual Meeting. IEEE Lasers and Electro-Optics Society 1999 Annual Meeting (Cat. No.99CH37009), 2003
In WDM systems, the impact of fiber nonlinearity can be detrimental: four wave mixing (FWM), cross phase modulation (XPM) and parametric gain (PG) are the main causes. Whereas FWM, XPM and single channel PG have been extensively studied, the PG impact on WDM systems was not yet investigated in detail.

Ultralow PDL WDM fiber couplers for WDM transmission systems

OFC '98. Optical Fiber Communication Conference and Exhibit. Technical Digest. Conference Edition. 1998 OSA Technical Digest Series Vol.2 (IEEE Cat. No.98CH36177), 2002
Summary form only given. We have presented the polarization-swapping method as a polarisation dependent loss (PDL) reducing technique for fused taper fiber couplers. The manufactured 1.48/1.55 /spl mu/m WDM fiber couplers have shown a small PDL of one tenth of that of conventional couplers.

Designing operational WDM networks

GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004
Network design tools are routinely used in practice to design optical networks that can carry a given set of traffic demands at the least cost The criteria used to route demands during design are often different from those used while routing in the operational network.

WDM-based packet networks

IEEE Communications Magazine, 1999
We discuss design considerations for wavelength division multiplexing (WDM)-based packet networks. In the near term, such networks are likely to consist of WDM links connected using some form of electronic multiplexing. The focus of this article is on the joint design of the electronic and optical layer with the objective of simplifying the network and

On routing in large WDM networks

Optical Switching and Networking, 2006
An important problem in WDM network design is to construct a logical topology and determine an optimal routing over that topology. Mixed Integer Linear Program (MILP) formulations to generate optimal solutions for this problem have been presented. Such formulations are computationally intractable, even for moderate sized networks.

SONET and WDM

2011
Synchronous Optical Networking (SONET) is a popular standard for fiber optic voice and data transmission. It was developed originally by Bellcore, the research and development arm of the local American phone companies in the late 1980s [60]. It was meant to be a standard for fiber optic connections between telephone switches.

OCDMA over WDM Transmission

2007 9th International Conference on Transparent Optical Networks, 2007
The optical code division multiple access (OCDMA) over wavelength division multiplexing (WDM) passive optical network (PON) system has been proposed as a potential candidate for gigabit-symmetric fiber-to-the- home (FTTH) services. Asynchronous OCDMA over WDM systems have been experimentally demonstrated using superstructured fiber Bragg gratings ...

Dimensioning of survivable WDM networks

IEEE Journal on Selected Areas in Communications, 1998
In this paper routing, planning of working capacity, rerouting, and planning of spare capacity in wavelength division multiplexing (WDM) networks are investigated. Integer linear programming (ILP) and simulated annealing (SA) are used as solution techniques. A complex cost model is presented.

Planning of WDM Ring Networks

Photonic Network Communications, 2000
The rapid introduction of wavelength division multiplexing (WDM) technology to cope with the increased bandwidth requirements of transmission networks has intensified the need for recovery mechanisms at the optical layer. A first step towards survivable optical networking will be seen through the introduction of optical rings.
