Product description

A PM low ratio tap (LRT) for tapping low power from a fiber signal path whilst maintaining polarization through the component, for wavelengths between 900 – 1700 nm.

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. PM LRT’s 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. PM LRTs can therefore be readily specified in a wide variety of applications, enabling rapid design cycles and new project builds. For other wavelengths or coupling ratios, please contact us.
