Product Description

 Variable VOA In-Line Fiber Optic Attenuator

Description:
Variable in-line Optical Attenuators (Adjustable in-line optical attenuator) are used to permit dynamic control of optical power levels in a fiber. It uses for precisely balancing the signal strengths in fiber circuits or balancing an optical signal when evaluating the dynamic range of the measurement system. With turning the knob by hand, attenuation value can be set up to 55dB.





Features:
Perfect environmental stability and reliability
High Precise attenuation value
Low additional loss
Flawless end face Wide attenuation range (variable)
Applications:
Subscriber loop
Fiber optical telecommunication system
Fiber optical sensor
Testing equipment
