Extended Wavelength Independent Coupler (EIC)
Extended Wavelength Independent Couplers (EIC) are passive optical devices which allow the distribution and combination of optical signals of a broad wavelength range. In difference to the established couplers of the WIC type EIC are designed for using additional wavelengths in the third optical window. The couplers are manufactured on the basis of an advanced Fused Biconcal Taper (FBT) technology to provide optimum performance and longtime stability.
