ABSTRACT:
A device for cleaning ends of optical fibers comprises a vessel intended to contain a rinsing fluid, in which the ends are to be inserted. A holder assembly is attached to the vessel and has a central element comprising a through-hole adapted to receive a fiber holder. The central element can be moved vertically in order to position the fiber holder at a predetermined distance from the surface of the rinsing fluid, so that only a predefined portion of an end portion of an optical fiber held by the fiber holder is emerged in the rinsing fluid. For a correct distance this will protect the primary coating of the optical fiber from being wet by the fluid. A light guide is mounted in the central element. Its lower end projects through a predetermined distance from the bottom surface of the central element. The upper end surface of the light guide has a lens shape and can be viewed by an operator, so that when moving the central element by turning an adjustment ring the change of coloring of the upper surface of the light guide will indicate a contact between the lower end and the liquid surface. A piezoelectrical vibrator is connected to the vessel for conveying ultrasonic vibrations thereto and transmits vibrations having a scanning frequency, the variation of frequency eliminating the risk of forming stationary nodes in the liquid where no cleaning effect is achieved.
