Patent Images
1. An fiber optic cable splice comprising:
- at least an input and an output optical fiber cable;
at least one capillary tube enclosing the ends of input and output optical fibers;
at least two metallic cable-splice bridging flanges inserted into the input and output optical fiber cable and enclosing the input and output optical fiber;
an index matching fluid placed inside of the capillary tube;
a protection tube enclosing the capillary tube;
first and second metallic crimping tubes enclosing the optical fiber cable and the cable-splice bridging flanges;
a third metallic crimping tube enclosing the ends of optical fibers, capillary tube and protection tube, the first and second crimping tubes, and the cable-splice bridging flanges.

Abstract
A new fiber optic cable splice for splicing optical fiber cables together and reconstructing fiber-optic cable that provide substantially enhanced reliability and broadened operating temperature range is disclosed. The disclosed cable splice offer reliable and user friendly solutions to applications in many harsh environments such as avionics, field vehicles, and defense related instrumentation. The cable splice consists of a preassembled one piece splice core and outer mechanical and thermal shielding layers. A simple splicing procedure and key fixtures are also disclosed.
