optic type meaning in Chinese

视觉型

In wavelength division multiplexing ( wdm ) optical communication networks , power equalization and adjustment between channels demand variable optical attenuator ( voa ) be capable of providing low power consumption , low insertion loss , polarization independence , integration compatibility and flatness in a wide wavelength range . among the presented voas , thermo - optic type owns superior polarization dependence upon electro - optic one , and thermo - optic voa can be driven with much lower power than micro - electro - mechanic system ( mems )
在波分复用( wdm )光通信网络中，多信道间的功率均衡和调整需要具有良好特性的光可变衰减器( voa ) ，这些特性包括：低功耗、低插入损耗、偏振无关、易于集成以及大波长范围内的通带平坦性。
