The development of an automated electro-mechanical equipment for the manu¬facture of tapered optical fiber is presented, using the fusion and stretching method [1]. The equipment is composed of three parts. The first part is for the stretching of the fibers, here implemented a system Constituted by two bases (mobile) that move in opposite directions, these movils support the ends of the fibers during the stretching process. The second part is for the fusion of the fiber, in this case a base with oscillatory movement from right to left along the fiber was implemented, this mobile supports the flame, product of the combustion of oxygen and the domestic gas, the zone optimum flame to soften the fiber has a width of 2mm. The third part corresponds to the electronics and the automation of the system. In the automation of the first system we basically used a stepper motor, a planetary reducer, an arduino one, a TB6560 driver, and control programs that contain the speed indicated above and parameters to enter to stretch the fiber. Similarly for the second system, in this case the use of the reducer was not necessary, since the movement of the flame does not have to be very slow. Experimentally, the appropriate ranges were determined for the stretching speed of 4mm/min, for the oscillation of the flame of 5,95mm/s and the temperature of approximately 850°C. Tapers were prepared with the electro-mechanical equipment built, for which the values of the heating length (L0), the parameter a, which controls the taper profile and the waist diameter of the fiber (dc). In chapter 4, two profiles of tapers elaborated following the protocol are presented, resulting that when a is equal to 0,5 and values near to it the taper profile is linear, for a equal to 0 the profile is shown exponentially. When comparing these profiles with the profiles obtained by simulation under the same parameters, it was observed that these coincide in the profile of the taper, waist length and waist diameter. The minimum loss of light in the thinning process was 30%, a taper regularly good for a equipment developed in a short time.The results obtained show that with the electro-mechanical equipment built, tapers can be prepared with an exponential, parabolic or linear profile, with waist diameter and taper length according to our requirements.
