Abstract
An optical assembly for use in an optical telecommunications system and method for aligning the optical assembly. The assembly uses a pair of ball bearings to support an optical fibre on a baseplate. The optical fibre is aligned with respect to an optical device and then the first ball bearing is inserted and welded in place. The fibre alignment is then fine tuned and the second ball bearing is inserted and welded in place, thereby providing a simpler and more accurate method of aligning an optical fibre to an optical device.
Claims8
An optical assembly comprising:
- a mount having a first surface;
- an optical fibre mounted in a tube disposed in said mount;
- a baseplate having a second surface in a non-parallel arrangement with respect to said first surface, to provide an angled region between said first and second surfaces;
- and
- a ball bearing fixedly disposed in said angled region, between said first and second surfaces, and having an outer surface in contact with said first and second surfaces.
An optical telecommunications system using an optical assembly comprising:
- a mount having a first surface;
- an optical fibre mounted in a tube disposed in said mount;
- a baseplate having a second surface in a non-parallel arrangement with respect to said first surface, to provide an angled region between said first and second surfaces;
- and
- a ball bearing fixedly disposed in said angled region, between said first and second surfaces, and having an outer surface in contact with said first and second surfaces.
An optical assembly comprising:
- a mount having a first surface;
- an optical fibre in a tube in said mount;
- a baseplate having a second surface;
- and
- a ball bearing,
- wherein said first surface and said second surface are situated with respect to one another to provide a wedge-shaped region between said first and second surfaces, and
- wherein said ball bearing is situated in said wedge-shaped region and fixed to said first surface and said second surface.
