Optical integrated network technologies for coping with traffic fluctuation and service diversification

We develop an optical integrated network technology to cope with the rapid traffic fluctuation and the data service diversification. An optical packet and circuit integrated (OPCI) node can provide flexible optical paths for high quality of service, and dynamic optical packets for best-effort service on the same infrastructure. In this paper, we present a compatibility with various optical formats in an OPCI node consists of low polarization-dependent loss optical switches with nanosecond-order switching-speed and burst-mode amplifiers with low gain-fluctuation.
