A Large-Capacity Optical Switch Design for High-Speed Optical Data Centers

Due to the emergence of high-speed applications, demand for more bandwidth has increased exponentially in last a few years. To serve each user for his demand very fast processing and propagation of data is desired. These two requirements of high-speed communication can be fulfilled using optical fiber technology. In the same view in past many optical switch designs have emerged with their respective advantages and disadvantages. This paper proposes a wavelength division multiplexing (WDM)-based switch incorporating arrayed waveguide grating (AWG) as wavelength router and fiber delay lines (FDL) to create optical buffer. Proposed switch design is compared with recent switch design and it is found that both in terms of BER and packet loss probability the performance of proposed design is much better in comparison to earlier designs.
