Abstract
An optical fiber expanded beam connector in which a spherical lens is held between a conical seat on a sleeve and a conical seat on a support for the bared optical fiber, the support being within the sleeve and having an external diameter less than the internal diameter of the sleeve to provide clearance therebetween which permits the support to move radially with respect to the axis of the sleeve. The fiber with its covering is secured to a body within the sleeve, the body being secured to the sleeve. In one embodiment, the support is a ferrule within a bushing which is secured to the body, the length of the bushing from the conical seat being large relative to the radial thickness of the clearance. In another embodiment, the support is a ferrule urged toward the lens by a spring between the ferrule and the body.
