为了降低光网络单元的成本预算，我们对下行的光载波进行了上行传输开关键控信号的重调制。
We also realize wavelength remodulation for carrying upstream on-off keying (OOK) data to reduce the cost budget at the optical network unit.
由于不同的光网络单元onu与光线路终端olt的距离不同，实际工作时到达接收端的信号的幅度，相位都相差很大。
Because the distances from different ONUs to OLT are different, the amplitudes and phases of the different signals will have significant difference when receiving the receive terminal.
