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.

 

 Application

  Network/BER testing

  Power meter calibration

  Link loss simulation

  Optical margin analysis

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 variations of input power.

Program Mode

User can preprogram frequently-used attenuations to reduce workload.
