OVA-50 Optical Variable Attenuator
Description:
OVA-50 Optical Variable Attenuator can precisely attenuate input optical signals at 1310/1490/1550/1625nm wavelengths and directly output defined stabilized optical signal. OVA-50 is applicable in various testing situations:
Features:
Direct Output Power Control:
Normal attenuator can only introduce and display an attenuation value, you need a separate power meter to measure or adjust the output power value of attenuated optical signal. Working like a combination of attenuator and power meter, OVA-50 Output Power Control mode enables direct setting of precise optical power level and can automatically stabilize output level without any interference by the variations of input power.
Program Mode:
User can preprogram frequently-used attenuations to reduce workload.
