780~850 1X2 Wideband PM Fiber Couplers

Product Description: 

Fused couplers are ideal components to split or combine light signals between two fibers over a wide wavelength and temperature range. They are constructed by fusing and tapering two fibers together. The fused polarization maintaining couplers have low excess loss, low polarization dependent loss, low back reflection, high stability, high reliability high extinction ratio and compact size.
