Abstract
A novel orthogonal modulation scheme combining frequency shift keying (FSK) for label at 2.5 Gb/s and pulse position modulation (PPM) for payload at 40 Gb/s is proposed in this paper. The transmission performance and some influencing factors of the modulation scheme are demonstrated by simulation. The results show that this modulation scheme can increase the balanced extinction ratio (ER) and decrease the influence of the deviation of balanced ER on the transmission performance, comparing with the traditional FSK-amplitude shift keying (ASK) orthogonal modulation scheme. In addition, this modulation scheme can apply a LiNbO3 Mach-Zehnder modulator to realize the FSK label erasure without additional optical sources.
