Abstract	The performances of the optical switching node are improved in synchronous network. To align switching node input flow on a clock signal we propose an alloptical synchronizer using optical components such as fiber Bragg gratings, circulators and single-sideband modulator. This architecture captures the latecomer signal in a loop and delivers it at the start of the next clock period. The system performances were evaluated and the effects of the attenuation and signal to noise ratio on the signal were demonstrated. We show that for 40Gbit/s bit rate, signals can be synchronized with an error smaller than 5% of the signal duration without reaching unacceptable signal distortions.
