Abstract
A submersible fiber optic lens assembly for use with a fiber optic cable having an end. The assembly includes a lens cap having a lens plate, a seal nut threadedly received within the lens cap, an O-ring radially sealing between the lens cap and the seal nut, a grommet received within the seal nut, and a compression nut received within the seal nut adjacent the grommet such that the grommet may be axially compressed between the seal nut and the compression nut to form a seal between the jacket and the seal nut. The fiber optic cable has a jacket, the jacket being received within the grommet prior to compression of the grommet. The lens plate has a reservoir formed on an inside surface, with a globule of gel located in the reservoir. Upon assembly, the end of the fiber optic cable is received within the gel. The O-ring seal and the grommet seal form an water tight cavity which is further defined by the reservoir and the seal nut. The cavity is filled by the gel.
