The 18 wavelength-selective switch (WSS) based on micro electro mechanical systems (MEMS) technology is proposed and fabricated with micro electromagnetic actuators  8 WXC prototype node is implemented by using 18 WSSs as building elements. The working principle and the configuration of the micro electromagnetic actuator are illuminated. By analysis  reflecting prisms and narrow-band thin films filters. And a 8  the property suits for the application when the inputs are 2V  and the best fiber-to-fiber insertion loss 5dB is gotten.
