An Optical Packet Switching System with a Novel Scheme for Using Optical OFDM Label Signal
采用OFDM信号作为标记的光分组交换方案

A novel optical packet switching scheme, in which an optical orthogonal frequency division multiplexing (OOFDM) signal was generated as a label, was proposed and experimentally demonstrated .The 10Gb/s OOK optical payload and the 2.5Gb/s OFDM optical label were produced by intensity modulation of two continuous waves with different wavelength, respectively. In the experiment, we obtained the eye diagrams of the payload, constellation diagrams of the label and the BER curves of the label and payload, when the optical packets were transmitted on optical fiber or not. It was experimentally demonstrated that the power penalties for the payload and the label after 40km fiber transmission were 1dB and 0.5dB, respectively. The scheme is easy to implement, so it can be used in an optical label switched network.
