Abstract
An apparatus comprising an acoustically resonant ultrasound launcher is provided for cleaning of optical fiber connectors and other optical fiber parts. The resonant ultrasound launcher is designed to transfer and to focus ultrasonic energy from an ultrasound transducer to a relatively small target area with high intensity. Specially designed fluid flow channels allow this apparatus to efficiently clean optical fiber connectors with an exposed end surface or with an end surface concealed in a connector adapter. Circuitry is provided to automatically track the frequency to enhance the ultrasound generation. Another circuitry is provided to program the sequence of the cleaning process, including washing, rinsing and drying.
