ABSTRACT:
A machine for mounting a ferrule on an optical fiber cable which includes a plurality of function units (11-17) arranged in a line, including a control and display unit (11) and an inserting unit (16) for inserting an optical fiber into a ferrule which has been injected with an adhesive; a plurality of pellets (21-29) for holding a ferrule and an optical fiber cable and traveling along the function units for circulation; a memory divided into a plurality of areas; a presence detector (13) for feeding the memory in a corresponding area with a failure signal if a ferrule or an optical fiber cable is not present on a pellet (23); an adhesive detector (15) for feeding the memory in a corresponding area with a failure signal if a predetermined amount of adhesive has not been injected into a ferrule; a projection detector (17) for feeding the memory in a corresponding area with a failure signal if a predetermined length of optical fiber does not project from a ferrule after the optical fiber has been inserted through the ferrule such that all of said failure signals are displayed when the pallet returns to the control and display unit.
