       PON按信号分配方式可以分为功率分割型无源光网络(PSPON)和波分复用型无源光网络(WDMPON)。目前,APON、BPON、EPON、GPON均属于PSPON。PSPON采用星型耦合器分路,上/下行传送采用TDMA/TDM方式,实现共享信道带宽,分路器通过功率分配将OLT发出的信号分配到各个ONU彩票计划神器上。WDMPON则是将波分复用技术运用在PON中,光分路器通过识别OLT发出各种波长,将信号分配到各路ONU。

       在WDM-PON中,波分复用器通常称为波长路由器,它解复用下行信号,并分配给指定的OUN,同时把上行信号复用到一根光纤,传输到OLT。波长分路器主要由数组波导光栅(AWG)构成。目前,在波长分路器实现中需要关注串扰、温度稳定性问题以及色散效应。
