Low bend loss optical fiber

Abstract

Disclosed is a low bend loss optical fiber including: a core; an inner layer disposed at outside of the core, which has a refractive index lower than a refractive index of the core, the refractive index of the inner layer gradually decreasing as it becomes farther from the core; and a trench layer disposed at outside of the inner layer, which has a lowest refractive index.

Description

[0001] priority [0002] This application claims the application titled "Low Bend Loss Optical Fiber" and assigned serial number No. 10-2008-0130295 filed with the Korean Intellectual Property Office on December 19, 2008 and the Korean Intellectual Property Priority to an application filed with the Office entitled "Low BendLoss Optical Fiber" and assigned Serial No. 10-2009-0111472, the contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to optical fibers, and more particularly to low bending loss optical fibers. Background technique [0004] At present, with the establishment of FTTH (fiber-to-the-home) user transmission service network with a rate of 100Mbps or higher and the rise of related service industries, the demand for enhanced bending-resistant optical fibers for broadband transmission is growing rapidly. [0005] The common passive optical network (PON) used to construct FTTH includes an optical line term...

Problems solved by technology

[0010] However, the problem is that conventional optical fibers have relatively poor optical properties in terms of light loss due to bending
