Method and apparatus for cleaning a fiber optic connector end face

摘要

Methods and apparatus for the removal of foreign matter, such as oil and dust, from the end faces of optical fiber and optical fiber connectors. Cleaning is effected by bringing carbon nanotube material into contact with an end face to create a differential adhesion in the proximity of the end face that more strongly attracts foreign matter residing on the end face to the carbon nanotube material than its attraction to the end face. The carbon nanotube material is applied with cleaning swabs or tapes that are used to clean end faces with swiping actions.

主权项

1. A swab for cleaning the end face of optical fibers and fiber optic connectors comprising:
an elongated handle by which the swab can be manually manipulated, said elongated handle having end surfaces generally perpendicular to the longitudinal dimension of said elongated handle, the cross-section of said end surfaces being dimensioned to be small enough to be inserted into the openings of female optical connectors where fiber end faces reside; and a material consisting of carbon nanotubes attached to at least one of said end surfaces of said longitudinal handle so that said carbon nanotubes can be brought gently into contact with a connector end face and moved with respect to it with said elongated handle, said material consisting of an array of carbon nanotubes to attract by differential adhesion unwanted foreign matter, that may be present on the optical fiber end face, to said carbon nanotubes so that, upon separation of said array of carbon nanotubes from the optical fiber end face, foreign matter is carried away with said material.
