Therefore, we utilize optical switch to switch over two routes P1 and P2 which are normal feeder fiber P1 and protecting fiber P2. Signal pass P1 and P2 and through 2X2 coupler, splitter, and 2X1 coupler into the drop fiber. Finally pass through WDM coupler and filter into ONU.

传输时利用光开关切换成两路路径P1和P2，分别为在正常下的P1馈线光纤和发生错误时切换成P2保护光纤，再经2X2耦合器、分歧器和2X1耦合器，进入终端光纤，最后经分波多工耦合器和滤波器后进入光网路单元。

The collector in dynatron of smooth Ou photosensitive or blast off extremely direct receive laden resistor to be able to satisfy lesser laden requirement; to be in of dynatron of smooth Ou photosensitive blast off extremely add dynatron enlarge drive, the push-pull type circuit that through two photoelectricity coupler makes and feedbacking through increasing photosensitive dynatron base, reach stronger laden capacity already, increased the interference rejection capacity of power interface, the outputs power inadequacy weakness that overcame smooth Ou, raise the switch rate of smooth Ou again, overcame the distributinging capacitance as a result of existence of smooth Ou oneself, cause an effect to transmitting speed.

在光耦光敏三极管的集电极或发射极直接接负载电阻即可满足较小的负载要求；在光耦光敏三极管的发射极加三极管放大驱动，通过两只光电耦合器构成的推挽式电路以及通过增加光敏三极管基极正反馈，既达到较强的负载能力，提高了功率接口的抗干扰能力，克服了光耦的输出功率不足的缺点，又提高光耦的开关速度，克服了由于光耦自身存在的分布电容，对传输速度造成影响。
