OPTICAL FIBER, OPTICAL TRANSMISSION LINE, AND METHOD FOR MANUFACTURING OPTICAL FIBER |
摘要 |
An optical fiber (1) includes (i) an inner core (111) whose refractive index distribution has an a profile, (ii) an outer core (112) which surrounds the inner core (111), and (iii) a clad (12) which surrounds the outer core (112). In the optical fiber (1), Rd is set to not less than 0.15, where Rd is a ratio of a refractive index difference between the outer core (112) and the clad (12) to a refractive index difference between a center part of the inner core (111) and the clad (12).
