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.

Features:

? Attenuation range: 2.5-60dB

? Direct output power control

? Working modes

? Output power control

? Absolute/relative attenuation setting

? Program (10 preset frequently-used attenuations)

? Adjust at step of 0.05/0.10/1.00/10.00 dB

? PC control via USB

? USB power charging

? Backlight

? Over 30 hours continuous operation

? Handheld, light and easy-to-use

? CE FCC certificates
