Fiber Optic Inline Variable Attenuator
In-line variable fiber attenuators are made using Beam Blocking technology and are suitable for polarization-maintaining fiber and single-mode fiber. The attenuation range of in-line variable fiber attenuators is up to 80 dB; input and output options are flexible, with different PM fibers and connector types available. The package is rugged and hermetically sealed, with excellent environmental adaptability. The input and output of in-line variable attenuators can use single-mode fiber or polarization-maintaining fiber, and the wavelength range can be selected within 400 nm~1625 nm. PM fiber filters use Panda-type PM fiber. If other types of PM fiber are required, please contact our sales staff.
