OVA-50 Optical Variable Attenuator can precisely attenuate input optical signals at 1310/1490/1550/1625nm wavelengths and directly output defined stabilized optical signals. OVA-50 is applicable in various testing situations:
●Network/BER testing
●Power meter calibration
● Link loss simulation
● Optical margin analysis
Normal attenuators can only introduce and display an attenuation value. You need a separate power meter to measure or adjust the output power value of an attenuated optical signal. Working like a combination of an 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 variations of input power.
User can preprogram frequently-used attenuations to reduce workload.
