手持式光衰减器
Hand-held Type Variable Optical Attenuator
该手持式光衰减器能够对光信号进行连续可变衰减。由于此衰减器主要是为了对激光系统进行在线测试,因此,该仪表适用于包含通信设备的数字体系(PDH、SDH)应用以及采用模拟调制(CATV)的系统中。
Our company’s hand-held type VOA can make optical signal have continuous variable attenuation. The main purpose of this kind of attenuator is to test laser system online, so this attenuator can applied to PDH, SDH and CATV system.
