It can also combine optical switching with the ATM(Asyn-chronous Transfer Model)switching when the speed of optical beam deflection reaches a level of nanosecond. So it can fulfil the demand for switching needed by high speed rate information network.

• 当光束偏转速度达到纳秒级时，该网络又可将光交换与ATM（异步转移模式）交换相结合，从而满足高速信息网络对交换的要求。
