摘要
本文研究了弯曲损耗与余长的关系,建立了一管多芯松套充油单模光纤的一种特定的弯曲模型,从而导出了弯曲损耗与光纤余长等参数的解析表达式,将弯曲损耗公式从Marcuse、Petermann的以弯曲半径为变量完善判断以光纤余长为变量,实验证明,理论模型与实验结果具有良好的一致性,为微束光纤光缆的研究、制造提供了一个简单可靠的理论依据。
In this paper, the relation between curvature loss and overlength of loose-tube optical fibers is investigated,a specical curvature model for multi-monomode fibers jacketed with a loose jelly-filled tube is given,an analytic expression for curvature loss in single-mode optic al fibers is derived from the model,which use overlength as a variable instead of optical fibers parameter. The formula provide an simple and reliable theory basis for us to study curvature loss in multi-monomode fibers jackted with a loose jelly-filled tube.
