Abstract : It has been obtained a single expression among magnitudes independently measured: core diameter and numerical aperture total maximum of the fibers to be spliced, and the loss of the arc fusion splice between them. This expression is suitable to be applied in junctions located in the proximity of the transmitter equipment, and whose optical and geometrical characteristics above mentioned are within of the tolerances of + or - 3 micrometer and + or - 0.02 respectively. Applying that expression it is possible: (a) To foresee, with a fair approach, the real losses of the splices; (b) To estimate a real acceptance range in the quality of splices to be made in plant, and (c) to choose the best values of arc current and time operation to do fusion splices in accordance with the optical nature of the fibers.
