Influence of the Laser Detuning and Optical Filter Cascading in WDM Networks

چکیده
The laser wavelength dependence on the temperature, polarization current, aging, can represent a problem in optical networks where multiple multiplexing and demultiplexing operations occur. These demultiplexing operations are commonly performed using fiber Bragg gratings, due to their versatility and unique filtering capabilities. In this contribution we evaluate the dependence of WDM networks performance, on the laser frequency misalignment and on the demultiplexers cascading, considering the demultiplexing operation performed by fiber gratings with different apodization types and distinct average index perturbations.

Conventional Wavelength Division Multiplexing (WDM) systems utilize narrowband coherent laser diodes as light source. These laser diodes are normally fabricated to be tunable over a wide range of wavelengths. With an increasing number of WDM channels, the number of laser diodes is also increasing and consequently the costs. Especially in the access network the use of spectral slicers is an attr...
متن کاملA Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks
Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of regeneration capabilities, the physical layer i...
