摘要： The transmission characteristics of the optical label switching system based on the FSK/ASK orthogonal modulation format is investigated. The factors that affect the transmission performance, such as the FSK tone space, dispersion compensation and coupler split ratio, are studied by numerical simulation. The proposed scheme is also experimentally demonstrated with a transmission of 155~Mbit/s FSK label combined with 10~Gbit/s ASK payload.

关键词: optical label switching, frequency shifted keying, amplitude shifted keying, dispersion compensation
