Abstract

See full text

To microscopically clean the ferrule end surface of an optical connector simply, uniformly and securely, the optical connector cleaner comprises a cleaning cloth woven with ultrafine fiber less than 0.1 denier; a casing formed with at least one opening for protecting the cleaning cloth from dust; and a mechanism for shifting the cleaning cloth exposed in the opening for cloth renewing, after the ferrule end surface has been rubbed with the cleaning cloth for cleaning. Further, it is preferable to provide an elastic member under the cleaning cloth for applying a constant cleaning pressure against the cloth and a guide member over the cleaning cloth for securely cleaning the ferrule end surface. The cloth shift mechanism is operated manually by the user or automatically by a motor. A holder jig holds the optical connector to facilitate cleaning of the ferrule end surface. The holder jig supports the optical connector such that the ferrule projects from the holder jig.
