Rotating disks stepping attenuation: stepping quantity 0.1 dB and stepping 2.5 dB optional
Having relatively attenuation values or absolute attenuation values
Hand-held Type Variable Optical Attenuator
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.
Features
Rotating disks stepping attenuation: stepping quantity 0.1 dB and stepping 2.5 dB optional
Having relatively attenuation values or absolute attenuation values
Having automatic shutdown function if no operation in 10 minut
