However, the effect of Fresnel reflection at a fiber— fiber connection can be reduced to a very low level through the use of an index-matching fluid in the gap between the jointed fibers.

Theoretical and experimental analysis of single mode fiber-to-fiber joint loss due to lateral misalignment. Over the past three decades, both fiber preparation and fiber alignment unimportant compared to the actual joint formation, loss estimation, or splice packaging. Unable to display preview.

However, the effect of Fresnel reflection at a fiber— fiber connection can be reduced to a very low level through the use of an index-matching fluid in the gap between the jointed fibers. Two lengths of the fiber with smooth and perpendicular to the core axes end faces are butted together. Assuming the fiber axes are perfectly aligned, calculate the optical loss in decibels at the joint due to Fresnel reflection when there is a small air gap between the fiber end faces.

Fiber alignment and joint loss. A major consideration with all types of fiber—fiber connection is the optical loss encountered at the interface. Even when the two jointed fiber ends are smooth and perpendicular to the fiber axes, and the two fiber axes are perfectly aligned, a small proportion of the light may be reflected back into the transmitting fiber causing attenuation at the joint.
