Abstract
A method and device for monitoring and minimizing the splicing losses at a splicing location for glass fiber cables characterized by a measuring cylinder which has a hinge to enable opening the cylinder up to place it around a splicing connection and has a photosensitive layer for converting a light escaping at the splicing location into an electrical signal and a device for evaluating the electrical signal. The photoelectric sensing device can be a continuous layer or a series of photoelectric elements electrically interconnected and the device for evaluating the electrical signal produced by the photoelectric sensing device preferably includes ear phones which converts the electrical signal into an accoustical signal and the light being applied to the cable is applied with a frequency in the audible frequency range of an ear. If a continuous light signal is sent or an extremely high frequency light signal, an electrical current measuring device can be utilized to evaluate the output of the sensing layer or elements.
