Research and Development of 160 Gbit/s/port Optical Packet Switch Prototype and Related Technologies

摘要

We have developed optical packet switch (OPS) prototype with optical code label processing, optical switching, optical buffering, and electronic scheduling to improve drastically the switching performance of optical packets in photonic network nodes. 160 Gbit/s/port OPS prototype is developed by introduction of 25 Gchip/s narrow-band optical code label processing and optical buffering with noise reduction function. A novel packet bit error rate (BER) and loss real-time measurement method and system for 40 Gbit/s variable-length packets has been proposed. Packet BER and loss real-time measurement with various conditions is experimentally demonstrated by using proposed measurement system and OPS system. By using the proposed system, only the payload data part of packet and burst data, which varies in interval time and packet length, is evaluated. Packet BER and loss real-time measurement with 160 Gbit/s variable-length OPS, OTDM-MUX/DEMUX, and 10 Gbit/s preamble free optical packet 3R receiver are experimentally demonstrated. Finally, integral demonstration by using 160 Gbit/s/port OPS prototype with optical buffer, packet BER evaluation system, and OTDM-MUX/DEMUX system with 160 Gbit/s and 10 Gbit/s light signal is reported.
