Abstract
A frequency of an ultrasonic cleaner for cleaning an optical fiber can be varied, thereby facilitating removal of particles of various sizes. The control of the varying may be predetermined or may be closed loop. The control may also alter the duration of the application of the frequency. A container which insures a set position of the fiber and/or immersion of the fiber in a cleaning solution may be employed. The sizes of particles on the fiber to be cleaned may be determined and parameters for cleaning may be selected in accordance with the determined sizes.
