Gooch & Housego’s FPU-xxxxxxAxx series of fused PM low ratio tap couplers tap off low power from a signal path whilst maintaining polarization through the component. Gooch & Housego (G&H) proprietary PM manufacturing technology provides tap ratios as low as 0.01% with ultra-low loss and high polarization extinction ratio.
The all-fiber construction and excellent loss characteristics provide exceptional reliability at high powers. FPU-X PM low ratio tap couplers also exhibit improved tap ratio stability when input polarization extinction ratio levels are low or fluctuating.
These high-performance parts are available at a range of wavelengths with different fiber options. FPU-X PM low ratio tap couplers can therefore be readily specified in a wide variety of applications, enabling rapid design cycles and new project builds. Standard parts are available at wavelengths from 900 – 1600 nm. For other wavelengths or coupling ratios please contact AMS Technologies.
