提出了一种新的相移键控（PSK）-曼彻斯特编码方案，并将其应用于10 Gb/s波分复用无源光网络（PON）系统中。与差分相移键控和幅移键控曼彻斯特信号相比，PSK-Manchester信号对差拍干扰噪声有更强的耐受性。采用这种调制格式，可以大大减少PON系统中用作控制门的半导体光放大器的数量，这使得PON系统更具成本效益。
Novel phase-shift-keying (PSK)-Manchester coding scheme is suggested for the first time to be used in a 10-Gb/s wavelength-division-multiplexing passive optical network (PON) system. PSK-Manchester signal demonstrates much stronger tolerance to beat interference noise compared to that of differential phase-shift-keying and amplitude-shift-keying-Manchester signals. With this modulation format applied, the number of semiconductor optical amplifiers used as control gates in a PON system can be greatly reduced, which make the PON system more cost-effective.
