Single mode bend insensitive fiber for use in fiber optic guidance applications. |
摘要 |
A doubl-clad single mode optical fiber with a depressed inner cladding (34) exhibits increased resistance to attenuation increases resulting from small radius bends and lower attenuation sensitivity to temperature changes when the mode field diameter is less than 7 um and the ratio of the radius of the inner cladding (34) to the radius of the core (32) is at least 6.5 to one.
