A frequency multiplexed routing and selecting hybrid switch for an optical cross-connect with wavelength scalability

We propose a new switch architecture: FRASH (frequency multiplexed routing and selecting hybrid) for the optical cross-connect node using space switching and WDM switching technologies. The FRASH switch consists of PI-LOSS (path-independent insertion loss) switches, star couplers and wavelength selectors. Then we show that the FRASH switch provides good scalability for wavelengths. Finally, we demonstrate the good performance of a 10 Gb/s signal transmission through the FRASH switch.
