随着光纤到户的发展,光纤的屋内配线成为一个必须解决的课题。文章就屋内配线对付孔光纤的利用进行了研究。研究对象为折射率引导型光子晶体光纤,该光纤具有一个常规的高折射率的纤芯,沿着纤芯的包层均匀地分布着数个通孔以达到抑制弯曲损耗的目的。通过对该光纤断面电界强度、弯曲损耗、长期可靠性的数值分析,发现所提出的付孔光纤可适用于半径小至10mm的屋内配线。付孔光纤在住宅及商业建筑中的利用具有广阔的前景。
With the development of fiber to the home, fiber optic wiring inside the house has become a must-solve issue. Article on the use of indoor wiring to deal with the hole fiber was studied. The research object is a refractive index guided photonic crystal fiber, which has a conventional core of high refractive index, and a plurality of through holes are evenly distributed along the cladding of the core to achieve the purpose of suppressing bending loss. Through the numerical analysis of the electrical strength, bending loss and long-term reliability of the cross-section of the optical fiber, it is found that the proposed subfay fiber can be applied to indoor wiring with a radius as small as 10 mm. Fu Kong fiber optic fiber in residential and commercial use of the building has broad prospects.
