We carry out an extensive experimental and theoretical study of the Josephson effect in S-N-S junctions made of a diffusive normal metal ~N! embedded between two superconducting electrodes ~S!. Our experiments are performed on Nb-Cu-Nb junctions with highly transparent interfaces. We give the predictions of the quasiclassical theory in various regimes on a precise and quantitative level. We describe the crossover between the short- and the long-junction regimes and provide the temperature dependence of the critical current using dimensionless units eRNI c /e c and k BT/e c , where e c is the Thouless energy. Experimental and theoretical results are in excellent quantitative agreement.
