Fiberoptic cables are currently assembled almost completely manually. Semiautomatic devices are available on the market for the premanufacturing process. After this process is completed, the ceramic ferrule of the connector is filled with glue, then the glass fiber is introduced into the ferrule hole. This assembly sequence is executed only manually at present. However, because no measuring systems are available for this purpose, manual assembly cannot ensure that the critical joining force will not be exceeded. If this happens, the fiber wftl break off. The fiber will be damaged and the connector win become waste.
