摘　　要：为提高密集波分复用系统在升级过程中信道带宽的利用率,提出了新型全光纤光学梳状滤波器,采用光纤传输耦合理论,详细分析了光谱输出。结果表明,当设置参数合理时,可以实现不等带宽交错滤波,窄带口和宽带口的透过带宽分别满足不同传输速率的要求。同时,分析了臂长差漂移对输出特性的影响。In order to improve the using rate of the channel bandwidth on dense wavelength division multi- plexing system in the upgrade process,an novel interleaver is proposed,by using optical fiber transmission coupling theory, the output spectrum of interleaver is analyzed in detail. The results show that interleaving un- equal bandwidth output waveform is achieved when the parameters are reasonable some value,bandwidth of narrowband and broadband respectively meet the different transmission rate,and the Influence of arm length difference drift on the output spectrum is also analyzed in detail.
