Original Shinewaytech Ova-50 Optical Variable Attenuator

Product Description

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:

• Network/BER testing
• Power meter calibration
• Link loss simulation
• Optical margin analysis

Features:

• Attenuation Range: 2.5-60dB
• Direct Output Power Control
• Working modes: 
       Output power control
      Absolute/relative attenuation setting
      Program (Preprogramming frequently-used attenuations)
• Adjust at step of 0.05/0.10/1.00/10.00 dB
• PC Control via USB
• Backlight
• Over 30 Hours Continuous Operation
• Handheld, Light and Easy-to-use
• CE FCC Certificates

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.
