摘　　要：再调制波分复用无源光网络(WDM-PON)系统是将ONU端的光源用调制器来替代,就可以不用再ONU端配置光源设备大大降低了成本,也能够达到ONU"无色化"的技术方案。主要有两种实现再调制WDM-PON的方案:一种是采用马赫曾德尔调制器的直接调制方式,另一种是采用RSOA的光环回的再调制方式。而其中主要的是基于RSOA的再调制的WDM-PON系统,由于RSOA自身的一些优点使得它特别适合于再调制WDM-PON系统。Re-modulated Wavelength division multiplexing passive optical network（WDM-PON） system uses Modulator to replace Optical transmitter on ONU side, so that we can no longer configuration the light source device on ONU-side and thus greatly reduce the cost, but also be able to reach the ONU ＂colorless＂ technology program. There are two main Re-modulated WDM-PON scheme： one is direct modulation scheme using a Mach-Zehnder modulator, and the other is the halo back modulation mode using RSOA. Re-modulation WDM-PON system Which is based on o RSOA is better, because RSOA own has many advantages which making it particularly suitable for re-modulated WDM-PON system.
