Wide band-width high NA optical fiber |
摘要 |
An optical fiber which comprises a core made of a glass material, a thin plastic cladding formed on the peripheral surface of the core and a plastic coating formed on the plastic cladding, and satisfies the conditions (1) a specific refractive index of cladding resin after curing being 0.970 to 0.985 times that of the core periphery at a practical wavelength at ambient temperature, (2) light transmission through the cladding resin after curing being 500 to 4000 dB/km at a practical wavelength, and (3) a coefficient of linear expansion of the cladding resin after curing being not larger than 2.0x10-4/ DEG C., which optical fiber has a wide band-width and high NA.
