Abstract:
Improved optical fiber coupling reliability is realized by improving structures and materials used at the fiber joint. When ceramic ferrules are used at the fiber joint, the penetration of a UV-cured optical adhesive between the ceramic ferrules and the fiber ends is avoided or prevented, while an anti-reflective coating, an uncured optical adhesive, or a refractive index matching gel may be applied between the ceramic ferrules. When glass ferrules are used at the fiber joint, the UV-cured optical adhesive may be applied and fully cured between the glass ferrules and the fiber ends.

Claim (Index 11):
A method for coupling optical fibers, the method comprising:\n connectorizing a proximal fiber into a first ferrule; connectorizing a distal fiber into a second ferrule at an interface between the first ferrule and the second ferrule; introducing a first ultraviolet (UV)-cured optical adhesive introduced in the interface; aligning the proximal fiber in the first ferrule and the distal fiber in the second ferrule in an alignment fixture, wherein a glass sleeve is pre-placed around one of the first ferrule or the second ferrule; sliding the glass sleeve over a fiber joint between the first ferrule and the second ferrule, wherein the glass sleeve extends over the first ferrule and the second ferrule; applying one of the first UV-cured optical adhesive and a second UV-cured optical adhesive to a first end of the glass sleeve to bond the glass sleeve to the first ferrule; applying one of the first UV-cured optical adhesive, the second UV-cured optical adhesive, and a third UV-cured optical adhesive to a second end of the glass sleeve to bond the glass sleeve to the second ferrule; wherein the fiber joint sustains a luminous flux of at least 70 lumens transmitted through the proximal fiber to the distal fiber without degradation for at least 30 minutes.
