ABSTRACT:
Methods tune all fiber loops in a loop back device to an established insertion loss value to produce a consistent overall loss of the loop back device. One method involves establishing a desired loss for fiber loops, securing the fiber loops to a MT ferrule, measuring an actual loss associated with each of the fiber loops, and comparing the actual loss with the desired loss. The method further involves changing a radius of a bend in any fiber loop where the actual loss is greater than or less than the desired loss until the actual loss associated with that fiber loop is substantially equal to the desired loss. Once the actual loss measured for the fiber loop is substantially equal to the established desired loss, the method secures the fiber loop to prevent a change in any radius of the bends.
