ABSTRACT:
Optical fiber communication systems require a light source to be coupled to a fiber with good alignment, with low risk of fiber breakage, and with a hermetic seal of around the coupling zone. Elastically deformable clamping and sealing rings around the fiber and within a metal sleeve housing the source are known. The invention employs two soft deformable rings spaced apart by a rigid bushing. The rings have conical surfaces compressed between corresponding conical surfaces in the sleeve. Axial alignment of the fiber is achieved with a minimum of interfaces to obtain a good seal.
