| Zusammenfassung: | A plastic glass optical fiber of the present invention includes a glass core (diameter a 1 , relative refractive index difference 1 , and refractive index n 1 ), a polymer core (diameter a 2 , relative refractive index difference A 2 , and refractive index n 2 ), and a polymer cladding (refractive index n 3 ), in which the diameter a 1 of the glass core is within a range of 110 µm to 200 µm, a parameter X (X is a 2 2 /a 1 2 ) is within a range of 1.15 ¤ X ¤ 2.9, a parameter Y (Y is 2 / 1 ) is within a range of 0.25 ¤ Y ¤ 0.84X - 0.68 (when 1.15 ¤ X ¤ 2) or 0.48X - 0.71 ¤ Y ¤ (2/9)X + 13/9 (when 2 ¤ X ¤ 2.9), a parameter Z R (Z R is Z 2core / Z 1core ; Z 2core = a 2 2 À/4 × (n 1 2 - n 3 2 ) and Z 1core = a 1 2 À/ 4 × (n 1 2 - n 2 2 )) is within a range of 1.25 ¤ Z R ¤ 4. According to this plastic glass optical fiber, bandwidth is equal to or greater than that of a single-layer core fiber, and large diameter and high NA are achieved while enhancing flexural resistance. |
