Abstract

On the international market there are some manufacturers of machines for polishing fiber optic connectors. These items of equipment, which typically polish from 6 to 12 connectors simultaneously, are extremely expensive as they are based on a very precise mechanical construction. In these machines, the polishing film rests on a platen which moves in the form of a figure eight or planetary figure (for the combination of the two movements). In the project proposed here, the objective is to develop a new type of machine, extremely compact, the platform of which will execute a random vibratory movement, similar to Brownian movement, although in macroscopic amplitudes. Proceeding in this manner, the optimal characteristics of the fiber connectors are achieved naturally, without the need for precision in the mechanical make-up of the parts. As far as is known, this idea is unique and the machine should be the object of an international patent. Depending on the results to be achieved, this same proposal could, eventually, be extended in three dimensions, simulating a Brownian agitator aimed at homogenizing mixtures for application in the chemical, pharmaceutical or biological business.
