MCDQDB (Multi-channel DQDB) using WDM (wavelength division multiplexing)
Proceedings of GLOBECOM '95, 2002Applications such as real-time video/voice service, distributed multimedia database access, and high-resolution image transfer require more bandwidth than is available today. These applications also require a large geographical span. To meet these requirements, we introduce the new protocol, MCDQDB, for a multi-channel dual-bus MAN which is the ...

Code division multiple access (CDMA) enhancement of wavelength division multiplexing (WDM) systems
Proceedings IEEE International Conference on Communications ICC '95, 2002Wavelength division multiplexing (WDM) is a mainstream technology for optical communications ranging from long haul applications to interconnections between and within high speed digital systems. WDM is, however, constrained (1) in density by the crosstalk associated with channel spacing and (2) by total number of channels which can be uniformly ...

Proceedings.Twenty-First Annual Joint Conference of the IEEE Computer and Communications Societies, 2003
We study routing and wavelength assignment for a circuit-switched time division multiplexed (TDM) wavelength-routed (WR) optical WDM network. In a conventional WR network, an entire wavelength is assigned to a given session (or circuit). This can lead to lower channel utilization when the individual sessions do not need the entire channel bandwidth. We

Bandwidth Reduction Technique for Multilayer Wavelength Division Multiplexing (WDM) Bandpass Filters
Applied Optics, 2000The push to develop 100 GHz and smaller bandwidth WDM filters is at demanding levels. Currently, 200 GHz is the standard bandwidth for multilayer interference coatings with high efficiencies, and enormous processing effort is going into the development of standard 100 GHz filters. This paper outlines a simple design that will reduce bandwidth up to 40%
