Cleaning Tool for Optical Subassemblies

       Disclosed is a tool for cleaning the lens of optical
subassemblies used in optical communication and data links.

      The Optical Subassembly (OSA) 6 contains a laser or LED and a
focusing lens 7.  The lens 7 must be free of any particles or film in
order to efficiently couple power or light into the transmission
fiber.  The surface of the lens is very small and difficult to access
inside the OSA.

      The cleaning tool 1 is shaped similar to the fiber-optic
connector that plugs into the OSA.  The cleaning tool contains either
a tube 2 with air nozzles 3 or with nylon brushes 4.  The air nozzles
3 with exhaust channels will plug into the OSA; air is then injected
through the inlets 5, which will blow any loose particles off the
lens surface.  Nylon brushes 4 also plug into the OSA, the tubes
holding the brushes being rotated, which will wipe away particles
that have adhered to the lens and remove any film from the lens
surface.

      Both methods may be used in conjunction or independently to
clean the lens.
