The dense wavelength division multiplexing (DWDM) technique has been developed to provide a tremendous number of wavelengths/channels in an optical fiber. In the multi-channel networks, it has been a challenge to effectively schedule a given number of wavelengths and variable-length packets into different wavelengths in order to achieve a maximal network throughput. This optimization process ha...
A 1 by 4 wavelength division multiplexer with 0.5nm bandwidth and no free spectral range limitation is demonstrated on silicon. The device utilizes wide bandwidth filters cascaded with ring resonators in order to select specific ring resonator modes and route each resonant mode to a separate port. This technology will enable dense wavelength division multiplexing covering the C - and L - bands ...
Optical Burst Switching (OBS) has been developed as an efficient switching technique to exploit the capacity provided by Dense Wavelength Division Multiplexing (DWDM) transmission technology for the next generation optical Internet. Segmentation is proposed in literatures to resolve contention, a major concern in optical burst switched networks. As far as segmentation is concerned, nearly all t...
We describe a model of Raman-parametric hybrid amplifier and present its simulation results for flat gain amplification in Dense Wavelength Division multiplexed (DWDM) terabits capacity system. In the proposed configuration single pump FOPA is cascaded after Raman to form a hybrid with each implemented in separate length of fiber. This allows for maximum optimization of gain achieved using Rama...
The tremendous growth of the high speed Internet and data traffic has created an enormous demand for transmission bandwidth of dense wavelength division multiplexed (DWDM) optical communication systems. With the advancement of wideband fiber-optical amplifiers, DWDM optical transmission systems are capable of providing capacities in excess of hundreds of gigabits per second over hundreds of kil...
-This presentation will discuss the relative merits of various monitoring schemes, and show that by providing faster turn-up time, minimizing dowii-time in case of ii fault and enabling performance optimization, optical domain performance monitoring provides cost savings to network operators. For applications applied in the Internet today, bit error requirements may be considerably alleviated a...
Introduction: Polarisation mode dispersion (PMD) is an important factor in the performance of long-distance high speed optical transmission systems. There is clearly a need for a practical approach that supports the network provider’s planning and route design process for possible capacity upgrading in existing fibre plants, such as to retrofit 10 Gbit/s dense wave division multiplexing (DWDM) ...
Aggregation of wavelengths into wavebands is an attractive, cost-efficient way to facilitate switching and routing in optical networks. In this paper, we study the waveband routing and wavelength assignment (WRWA) tasks in hierarchical WDM mesh networks with optical crossconnects that can route multiple granularity (wavelengths and wavebands) at the same time. We solve the waveband routing and ...
