Abstract

fibra óptica com baixa perda por curvatura. trata-se de uma fibra óptica com baixa perda por macro e microcurvatura. a fibra possui uma primeira região de revestimento interna, com raio externo r~2~ > 8 1<a>m e índice de refração <30>~2~, e uma segunda região de revestimento externa que circunda a região de revestimento interna, com índice de refração. <30>~3~, onde <30>~1~ > <30>~3~ > <30>~2~. a diferença entre <30>~3~ e <30>~2~ é maior que 0,01. a fibra apresenta um corte de cabo 22 m menor ou igual a 1.260 nm e r~1~/r~2 maior ou igual a 0,25.
