Key Features
FVA is a series of continuously adjustable fiber attenuators. Fuxiang FVA is a precision mechanical device controlling fiber light intensity, with SMA905 connections at both ends. Turning the nylon nut moves an internal slit, covering 200nm-2000nm with control from 0-100%, attenuating strong signals to prevent spectrometer saturation. Compact size and standard interfaces suit flexible laboratory fiber spectroscopy and large inspection equipment. Ultrawide spectral coverage avoids component changes between bands. Continuous 0~100% adjustment controls system input/output intensity. Standard SMA905 interfaces support different fiber cores, with custom interfaces available.
