Abstract
Recent development of ultra high-speed optical code-label processing and its application to packet switching are reported. 10 to 40Gbit/s interface, scalable, optical packet switch prototype based on optical code-label processing is developed. Optical packet switching with 200Gchip/s all-optical label processing, 10 to 40Gbit/s/port variable data rate packet switching, and optical buffering to avoid packet collisions is experimentally demonstrated. A novel packet bit error rate (BER) and loss real-time measurement method is proposed. The first 40Gbit/s packet BER and loss measurement system is shown. 40Gbit/s BER and loss evaluation with various conditions is experimentally demonstrated. In real time, only the payload part of packet and burst stream with fluctuated interval time is evaluated. BER and packet loss of randomly received packet sequence because of routing and buffering can be also evaluated by the proposed system. 10Gbit/s packet BER and loss measurement with optical label switching, buffering, and preamble free optical packet 3R are experimentally demonstrated.
