Abstract:
1. A method for tuning a loop back device to an established loss consistent among all fiber loops in the loop back device, the method comprising: a) establishing a desired loss value for the fiber loops of the loop back device; b) securing ends of fibers of the fiber loops to a multiple termination (MT) ferrule; c) measuring an actual loss value associated with one of the fiber loops; d) comparing the actual loss value with the established desired loss value; e) when the actual loss value is greater than the established desired loss value, increasing a radius of a bend in the one of the fiber loops until the actual loss value associated with the one of the fiber loops is substantially equal to the established desired loss value; f) when the actual loss value is less than the established desired loss value, decreasing the radius of the bend in the one of the fiber loops until the actual loss value associated with the one of the fiber loops is substantially equal to the established desired loss value; and g) when the actual loss value is substantially equal to the established desired loss value, securing the one of the fiber loops to prevent a change in the radius of the bend in the one of the fiber loops such that the actual loss value associated with the one of the fiber loops remains substantially equal to the established desired loss value; and h) repeating c) through g) for each of the fiber loops in the loop back device.
