LONG LENGTH FLUORIDE OPTICAL FIBER

THIS PROPOSAL IS ADDRESSING THE PROBLEMS OF DRAWING DEFECT-FREE LENGTHS OF FLUORIDE FIBER (> 500 M) WITH GOOD STRENGTH AND MECHANICAL PROPERTIES. SPECTRAN HAS EXTENSIVE EXPERIENCE IN BULK HMFG AND HAS RECENTLY ESTABLISHED A FIBER DRAW FACILITY FOR FLOURIDE FIBER. WE PROPOSE TO USE THE PREFORM TECHNIQUE APPROACH WITH INCREASED PREFORM AND INCREASED PREFORM LENGTH IN ORDER TO DRAW DECREASED FIBER LENGTHS. BY CAREFULLY CONTROLLING THE PREFORM CASTING TECHNIQUE, RAW MATERIALS, MOLD MATERIALS AND FIBER DRAW PARAMETERS, WE BELIEVE WE CAN ACHIEVE THE FIBER LENGTHS IN EXCESS OF 1 KM AND MORE.
