A Franson-type test of the Bell-inequality is presented. Energy and time entangled photons at wavelengths of 704 and 1310 nm are produced by parametric downconversion in KNbO3 and are sent through optical fibers into a bulk-optical (704 nm) and a fiber-interferometer (1310 nm), respectively. The two interferometers are located 35 meters aside from one another. Using Faraday-mirrors in the fiber-interferometer, all birefringence effects in the fibers are automatically compensated. Two-photon fringe visibilities up to 95% are obtained, yielding a clear violation of Bell's inequality by 8 standard deviations.
