Customized Variable Fiber Optic VOA In-Line Attenuator 0-60dB
Attenuators are used to control the optical power in a fiber. They are often combined with an active system component to maintain a desired optical power on a network even if the power of the input signal is changing.
Variable in-line optical attenuators comprises a dual fiber collimator and a reflection component separated by a linear moveable ND filter. They are used to permit dynamic control of optical power levels in a fiber and can be applied to adjust power level of signal in the optical communication at the output of light sources, E/O converters and for the linear or dynamic range of power meter.
All our attenuators are manufactured according to industry standards and are 100%fully tested.
Operation of Variable Optical Attenuator
Narrowband VOAs
For the narrowband VOAs, turning the adjustment screw moves the blocking device up and down in order to achieve the desired attenuation.
Fiber Type:SMF-28
Attenuator Design:LC UPC to LC UPC
Attenuation Value:0dB ~ 30dB
Cable lengths:2 meters
Broadband VOAs
For the broadband VOAs, turning the adjustment screw rotates the window, causing a beam path deviation that changes the coupling efficiency into the output fiber.
Fiber Type:SMF-28
Attenuator Design:LC UPC to LC UPC
Attenuation Value:0dB ~ 30dB
Cable lengths:2 meters
